Light rail is usually not the solution you need for better public transit

Filed under: Economics, Railways, USA — Tags: , , — Nicholas @ 03:00

At Coyote Blog, a look at the new Phoenix light rail system’s miraculous ability to stall the growth in public transit usage:

As I have written before, Phoenix has seen its total transit ridership flat to down since it built its light rail line. This after years of 6-10% a year increases in ridership. Most cities, even the oft-worshipped Portland, has seen the same thing. Here is the chart for Phoenix (if you look closely, you can see how they fudged the bar scaling to make light rail ridership increases look better).

Phoenix light rail ridership

The reason is that per passenger, or per mile, or per route, or whatever way you want to look at it, rail systems are 1-2 orders of magnitude more expensive than buses. Since most cities are reluctant to increase their spending on transit 10-100x when they build trains (and to be fair, proponents of rail projects frequently make this worse by fibbing about future costs and revenue expectations), what happens is that bus routes are cut to fund rail lines. But since buses are so much cheaper, 10 units of bus capacity, or more, must be cut for each one unit of rail capacity.

[…]

By the way, beyond the obvious harm to taxpayers, the other people hurt by this are the poor who are disproportionately bus users. Rail systems almost always go from middle/upper class suburbs to business districts and seldom mirror the transit patterns of the poor. Middle class folks who wouldn’t be caught dead on a bus love the trains, but these same folks already have transportation alternatives. The bus lines that get cut to fund the trains almost always serve much lower income folks with fewer alternatives.

This comment from slocum may show the hidden intent in many cities’ drive to replace bus routes with light rail services:

BTW, am I the only one who suspects that there might be a little method to the madness of building light rail and cutting back on bus service? Isn’t it a pretty effective way to drive gentrification by making cities more attractive to the well-off and less so to the poor?

Come for the shiny new light rail system. Stay for the snobbery and active shunning of the poor!

QotD: Impressions of Dresden

Filed under: Europe, Germany, Humour, Quotations, Railways — Tags: , , — Nicholas @ 01:00

We reached Dresden on the Wednesday evening, and stayed there over the Sunday.

Taking one consideration with another, Dresden, perhaps, is the most attractive town in Germany; but it is a place to be lived in for a while rather than visited. Its museums and galleries, its palaces and gardens, its beautiful and historically rich environment, provide pleasure for a winter, but bewilder for a week. It has not the gaiety of Paris or Vienna, which quickly palls; its charms are more solidly German, and more lasting. It is the Mecca of the musician. For five shillings, in Dresden, you can purchase a stall at the opera house, together, unfortunately, with a strong disinclination ever again to take the trouble of sitting out a performance in any English, French, or, American opera house.

The chief scandal of Dresden still centres round August the Strong, “the Man of Sin,” as Carlyle always called him, who is popularly reputed to have cursed Europe with over a thousand children. Castles where he imprisoned this discarded mistress or that — one of them, who persisted in her claim to a better title, for forty years, it is said, poor lady! The narrow rooms where she ate her heart out and died are still shown. Chateaux, shameful for this deed of infamy or that, lie scattered round the neighbourhood like bones about a battlefield; and most of your guide’s stories are such as the “young person” educated in Germany had best not hear. His life-sized portrait hangs in the fine Zwinger, which he built as an arena for his wild beast fights when the people grew tired of them in the market-place; a beetle-browed, frankly animal man, but with the culture and taste that so often wait upon animalism. Modern Dresden undoubtedly owes much to him.

But what the stranger in Dresden stares at most is, perhaps, its electric trams. These huge vehicles flash through the streets at from ten to twenty miles an hour, taking curves and corners after the manner of an Irish car driver. Everybody travels by them, excepting only officers in uniform, who must not. Ladies in evening dress, going to ball or opera, porters with their baskets, sit side by side. They are all-important in the streets, and everything and everybody makes haste to get out of their way. If you do not get out of their way, and you still happen to be alive when picked up, then on your recovery you are fined for having been in their way. This teaches you to be wary of them.

Debunking the “GM killed the streetcars” conspiracy theory

There are many railfans who still believe, strongly and passionately, that General Motors was involved in a devious plot to kill off the streetcars across North America in order to sell more buses. At Vox.com, Joseph Stromberg explains that this wasn’t the case — in fact, the killer of the streetcar/interurban/radial railway systems was their willingness to lock in to long-term uneconomic agreements with local governments in exchange for monopoly privileges:

Back in the 1920s, most American city-dwellers took public transportation to work every day.

There were 17,000 miles of streetcar lines across the country, running through virtually every major American city. That included cities we don’t think of as hubs for mass transit today: Atlanta, Raleigh, and Los Angeles.

Nowadays, by contrast, just 5 percent or so of workers commute via public transit, and they’re disproportionately clustered in a handful of dense cities like New York, Boston, and Chicago. Just a handful of cities still have extensive streetcar systems — and several others are now spending millions trying to build new, smaller ones.

So whatever happened to all those streetcars?

“There’s this widespread conspiracy theory that the streetcars were bought up by a company National City Lines, which was effectively controlled by GM, so that they could be torn up and converted into bus lines,” says Peter Norton, a historian at the University of Virginia and author of Fighting Traffic: The Dawn of the Motor Age in the American City.

But that’s not actually the full story, he says. “By the time National City Lines was buying up these streetcar companies, they were already in bankruptcy.”

Surprisingly, though, streetcars didn’t solely go bankrupt because people chose cars over rail. The real reasons for the streetcar’s demise are much less nefarious than a GM-driven conspiracy — they include gridlock and city rules that kept fares artificially low — but they’re fascinating in their own right, and if you’re a transit fan, they’re even more frustrating.

This is one of the reasons I’m generally against new plans to re-introduce streetcars (or their modern incarnations generally grouped under the term “light rail”), because they fail to address one of the key reasons that the old street railway/interurban/radial systems died: they were sharing road space with private vehicles. Light rail can provide a useful urban transportation option if they have their own right-of-way, but not if they are merely adding to the gridlock of already overcrowded city streets.

And once again, I’m not anti-rail … I founded a railway historical society and I commute most work days on a heavy rail commuter network. I don’t hold this position due to some anti-rail animus. If anything, I regret the passing of railway systems more than most people do, but I recognize that they have to be self-supporting (or close to self-supporting) to have a chance to survive. Being both more expensive and less convenient than alternative transportation options is a sure-fire path to extinction.

Al Stewart – “Trains”

Filed under: Britain, Europe, History, Railways — Tags: — Nicholas @ 03:00

Published on 19 Mar 2013

In the sapling years of the post-war world in an English market town
I do believe we travelled in schoolboy blue, the cap upon the crown
Books on knee; our faces pressed against the dusty railway carriage panes
As all our lives went rolling on the clicking wheels of trains

The school years passed like eternity and at last were left behind
And it seemed the city was calling me to see what I might find
Almost grown, I stood before horizons made of dreams
I think I stole a kiss or two, while rolling on the clicking wheels of trains

Trains…
All our lives were a whistle stop affair; no ties or chains
Throwing words like fireworks in the air, not much remains
A photograph in your memory, through the colored lens of time
All our lives were just a smudge of smoke against the sky

The silver rails spread far and wide through the nineteenth century
Some straight and true, some serpentine, from the cities to the sea
And out of sight of those who rode in style, there worked the military mind
On through the night to plot and chart the twisting paths of trains

On the day they buried Jean Jaures, World War One broke free
Like an angry river overflowing its banks impatiently
While mile on mile the soldiers filled the railway stations’ arteries and veins
I see them now go laughing on the clicking wheels of trains

Trains…
Rolling off to the front across the narrow Russian gauge
Weeks turn into months and the enthusiasm wanes
Sacrifices in seas of mud, and still you don’t know why
All their lives are just a puff of smoke against the sky

Then came surrender; then came the peace
Then revolution out of the east
Then came the crash; then came the tears
Then came the thirties, the nightmare years
Then came the same thing over again
Mad as the moon, that watches over the plain
Oh, driven insane

But oh, what kind of trains are these, that I never saw before
Snatching up the refugees from the ghettoes of the war
To stand confused, with all their worldly goods, beneath the watching guards’ disdain
As young and old go rolling on the clicking wheels of trains

And the driver only does this job with vodka in his coat
And he turns around and he makes a sign with his hand across his throat
For days on end, through sun and snow, the destination still remains the same
For those who ride with death above the clicking wheels of trains

Trains…
What became of the innocence they had in childhood games
Painted red or blue, when I was young they all had names
Who’ll remember the ones who only rode in them to die
All their lives are just a smudge of smoke against the sky

Now forty years have come and gone and I’m far away from there
And I ride the Amtrak from New York City to Philadelphia
And there’s a man to bring you food and drink
And sometimes passengers exchange a smile or two rolling on the humming wheels
But I can’t tell you if it’s them or if it’s only me
But I believe when they look outside they don’t see what I see
Over there, beyond the trees, it seems that I can just make out the stained
Fields of Poland calling out to all the passing trains

Trains…
I suppose that there’s nothing in this life remains the same
Everything is governed by the losses and the gains
Still sometimes I get caught up in the past, I can’t say why
All our lives are just a smudge of smoke, or just a breath of wind against the sky

The trains of war – the military application of steam power

Navvies working on the Grand Crimean Central Railway, 1854. Charles Walker: Thomas Brassey, Railway Builder, 1969. (via Wikipedia)

Trains were cutting-edge weapons of war in the 19th century — and all the major powers were figuring out how to deploy them. The Europeans learned how to move troops by train. The Americans — how to fight on rail cars. The British, meanwhile, found they could dominate an empire from the tracks.

In today’s world of tanks, bombers and submarines, it’s perhaps hard to believe that the train was once an amazingly mobile weapons platform. They might be locked to their rails, but for over a century trains were the fastest means of hauling troops and artillery to front lines across the world.

The invention of the railway shaped warfare for a century. Rails allowed force projection across immense distances — and at speeds which were impossible on foot or by horse.

[…]

The first demonstration of the military efficacy of the railroads was the 1846 Polish Uprising. Prussia rushed 12,000 troops of the Sixth Army Corps, with guns and horses, to the Free City of Krakow to help put down the Polish rebellion. In this period of nationalist uprisings, Russia and Austria also used their railroads against similar uprisings from 1848 to 1850.

A lack of infrastructure and experience stifled the success of these early endeavors. Due to a lack of rolling stock, suitable platforms and double-track stretches, the trains sometimes operated far slower than a man could march on foot.

Austria was first to get it right. In 1851, the Austrian Empire shuttled 145,000 men, nearly 2,000 horses, 48 artillery pieces and 464 vehicles over 187 miles.

Solving the Amtrak problem requires thinking outside the box … really outside

Filed under: Railways, USA — Tags: , , — Nicholas @ 05:00

At The Federalist, Sean Davis explains why throwing more taxpayer money at Amtrak isn’t going to do much good:

“Amtrak doesn’t get enough government money,” is the kind of thing someone says when that person doesn’t understand anything about Amtrak, or government, or money.

Created by Congress in 1970, Amtrak was meant to replace the private rail companies that, according to Amtrak, “had operated services at a net loss of millions of dollars for many years.” Net losses of millions of dollars, you say? According to its unaudited financial statements, Amtrak lost over a billion dollars in 2014, the last year for which annual revenue and expense data are available.

Amtrak lost nearly $1.3 billion in 2013. Since its creation, Amtrak has racked up over $31 billion in accumulated losses. And every penny of those losses has been covered by federal taxpayers.

Amtrak has a lot of problems. A lack of taxpayer generosity is not one of them, not even close. The key to fixing Amtrak, to making it function as a “for-profit corporation,” which is how the Federal Railroad Administration, Amtrak’s overseer, officially describes the passenger rail organization, is not increasing the volume of federal cash it sucks up every year. The solution is not to reform this and that to make the government-owned company work better or more efficiently. And selling off its assets to the highest bidder won’t fix Amtrak, either.

No, the key to fixing Amtrak is to just give it away. Hand over the entire enterprise to whichever rail company wants it. “But that’s crazy!” you might say. “Giving it away for free makes no cents!”

Why are railroads dragging their feet over more efficient braking systems?

Filed under: Government, Railways, Technology, USA — Tags: — Nicholas @ 03:00

Fred Frailey discusses the U.S. Department of Transportation mandate that all crude oil trains longer than 69 cars must be equipped with electronic brakes by 2021 or they will restrict the speed of oil trains to 30 MPH at all times. The current standard braking system for railroads in North America is pneumatic, which have worked well for decades, but have inherent problems as modern trains have gotten longer and heavier. One of the biggest problems is that pneumatic brakes have a relatively long activation time — when the engineer operates the brake in the lead locomotive, it takes quite some time for that to propagate all the way through the train. This creates situations which can cause derailments as the lead cars begin to slow down, while the rest of the train is still travelling at full speed.

The preferred replacements are called electronically controlled pneumatic brakes (ECP), where instead of the brakes operating by pressure changes in the air line, the brakes would be controlled by a separate electronic circuit that would allow simultaneous brake application in all cars in the train.

It seems electronic braking has no friends in the railroad industry. I find this puzzling. Research I’ve read suggests there is both a safety and business case to be made. One explanation for the bum’s rush being given ECP comes from someone whose career was immersed in railroad technology: “The mechanical departments say the ECP brakes don’t save enough on wheels and brake shoes to justify implementation. The track departments say that ECP brakes don’t reduce rail wear enough to justify implementation. Transportation departments say that ECP brakes don’t save enough fuel to justify implementation. And improved train running times, improved train dynamics, and improved engineer performance are all soft-dollar savings which don’t count. No one ever bothers to sum up total benefits.” Silos, in other words.

So I’ll make the case for ECP. (By the way, the standards were developed two decades ago by the same AAR that now vigorously opposes their implementation.) A train equipped with electronic braking is hard-wired, allowing instant communication from airbrake handle in the locomotive to every brake valve on the cars. The principal advantages are that all brakes instantly apply and release at the same time, the air supply is continually charged, engineers can gradually release and reapply brakes, and undesired emergency braking (dynamiters, they’re called) virtually disappear. In-train forces, such as slack roll-in and roll-out, are greatly reduced, and that lessens the risk of derailment. Moreover, stopping distance is reduced 40 to 60 percent, permitting higher train speeds and higher speeds approaching restricting signals. Longer trains are possible. Longer trains run at higher speeds increase the capacity of the railroad network. Because air is always charging, braking power is inexhaustible; plus, a train can stop and instantly restart. Brakes, draft gear, wheels, and bearings require less maintenance. Existing federal regulations would allow train inspections every 5,000 miles instead of the present 1,500 or 1,000 miles.

Those are a lot of advantages. In a report commissioned by the Federal Railroad Administration in 2005, the consulting company Booz Allen Hamilton estimated the cost of full implementation of ECP at $6 billion and the measurable savings (not including added network capacity) at $650 million a year. Booz recommended that ECP conversion begin with coal trains loaded in Wyoming’s Powder River Basin, then to other types of unit trains (presumably including intermodal trains), and finally the rest of the car fleet — all in a 15-year time frame. “As applied to western coal service,” its report stated, “the business case is substantial,” with a recovery of all costs within three years.

[…]

Several things are going on here. Silos are one. Nobody is looking at the big picture, just his or her little piece of it. The boys in the Mechanical Silo could care less about increased network capacity. The occupants of the Finance Silo don’t want to divert cash flow away from share buybacks, their favorite toy. Most of those in the CEO Silo didn’t come up on the operating side and are probably bored by the subject. In a conservative, mature business like railroading, risk taking and even forward thinking are not rewarded. And the cost of hard-wiring the car fleet would primarily be borne by shippers, who own most of the equipment, whereas railroads would reap the benefits. How to share the benefits with car-owning shippers leads to very difficult negotiations.

Professor: New UK railway signalling system is hackable … while he’s also selling anti-hacking gear

Filed under: Britain, Railways, Technology — Tags: — Nicholas @ 04:00

At The Register, John Leyden offers a bit of doubt that Professor David Stupples can really be said to be an impartial observer:

The rollout of a next generation train signalling system across the UK could leave the network at greater risk of hack attacks, a university professor has claimed.

Prof David Stupples warns that plans to replace the existing (aging) signalling system with the new European Rail Traffic Management System (ERTMS) could open up the network to potential attacks, particularly from disgruntled employees or other rogue insiders.

ERTMS will manage how fast trains travel, so a hack attack might potentially cause trains to move too quickly. UK tests of the European Rail Traffic Management System have already begun ahead of the expected rollout.

By the 2020s the system will be in full control of trains on mainline routes. Other countries have already successfully rolled out the system and there are no reports, at least, of any meaningful cyber-attack to date.

Nonetheless, Prof Stupples is concerned that hacks against the system could cause “major disruption” or even a “nasty accident”.

ERTMS is designed to make networks safer by safeguarding against driver mistakes, a significant factor historically in rail accidents. Yet these benefits are offset by the risk of hackers manipulating control systems, Prof Stupples, of City University London, warned.

Debunking the myths about the destruction of NYC’s Penn Station

Filed under: Architecture, History, Railways, USA — Tags: , — Nicholas @ 03:00

I admit up front that I’m a fan of railway architecture, so I readily followed along with the narrative that the wanton destruction of Penn Station in New York City was merely the most recent vandalic excess of the urban rejuvenation movement. Jim Epstein suggests that I was wrong:

Penn Station 1910In all the hoopla surrounding the 50th anniversary of New York’s Landmarks Preservation Act — Mayor Robert F. Wagner signed the legislation exactly a half century ago today — you’ll see plenty of photos of the old Penn Station taken around the time of its 1910 opening. These images depict the grand, light-filled main hall modeled after the Baths of Caracalla and the spectacular iron-and-glass train shed in its pristine state. Another series of photos shows the station being taken apart in the 1960s. In this set of images, the station looks like an ancient Roman palace; it’s as if the cranes pulling it apart are destroying the very bedrock of Western civilization.

“Seven-year-olds gasp…[when] we show them the old Penn Station,” Tara Kelly, the executive director of Friends of the Upper East Side Historic Districts, told the New York Times at an event last week celebrating the law’s half-centennial.

Penn Station 1910-2Penn Station’s destruction in the mid-1960s was a call to arms for the landmarks movement, leading directly to the passage of the 1965 law. Preservationists trot out these photos capable of leaving second graders breathless to remind us of why we need a government-appointed commission to save our historic buildings from cold market logic.

But this narrative is as one-sided as those photos. Profit-driven developers left to their own devices value wonderful old buildings as much as the general public they serve, but the old Penn Station was a deeply flawed structure. It emphasized form over function, so it was never a particularly good train station. And New Yorkers didn’t care for it very much — when it was still around, at least. It’s easy to revere the dead.

Regulating the US railroads

Filed under: Business, Government, History, Railways, USA — Tags: , , — Nicholas @ 02:00

At Slate Star Codex, Scott Alexander recently reviewed David Friedman’s latest revision to his 1973 book, The Machinery of Freedom (sometimes called The Machinery of Friedman by libertarian wags). Scott wasn’t totally sold on Friedman’s proposals, but he posted several highlights from the book, including this discussion of how the US government was persuaded to regulate the railroad industry and then the airlines:

One of the most effective arguments against unregulated laissez faire has been that it invariably leads to monopoly. As George Orwell put it, “The trouble with competitions is that somebody wins them.” It is thus argued that government must intervene to prevent the formation of monopolies or, once formed, to control them. This is the usual justification for antitrust laws and such regulatory agencies as the Interstate Commerce Commission and the Civil Aeronautics Board.

The best historical refutation of this thesis is in two books by socialist historian Gabriel Kolko: The Triumph of Conservatism and Railroads and Regulation. He argues that at the end of the last century businessmen believed the future was with bigness, with conglomerates and cartels, but were wrong. The organizations they formed to control markets and reduce costs were almost invariably failures, returning lower profits than their smaller competitors, unable to fix prices, and controlling a steadily shrinking share of the market.

The regulatory commissions supposedly were formed to restrain monopolistic businessmen. Actually, Kolko argues, they were formed at the request of unsuccessful monopolists to prevent the competition which had frustrated their efforts.

[…]

It was in 1884 that railroad men in large numbers realized the advantages to them of federal control; it took 34 years to get the government to set their rates for them. The airline industry was born in a period more friendly to regulation. In 1938 the Civil Aeronautics Board (CAB), initially called the Civil Aeronautics Administration, was formed. It was given the power to regulate airline fares, to allocate routes among airlines, and to control the entry of new firms into the airline business. From that day until the deregulation of the industry in the late 1970s, no new trunk line — no major, scheduled, interstate passenger carrier — was started.

The CAB had one limitation: it could only regulate interstate airlines. There was one major intrastate route in the country — between San Francisco and Los Angeles. Pacific Southwest Airlines, which operated on that route, had no interstate operations and was therefore not subject to CAB rate fixing. Prior to deregulation, the fare between San Francisco and Los Angeles on PSA was about half that of any comparable interstate trip anywhere in the country. That gives us a good measure of the effect of the CAB on prices; it maintained them at about twice their competitive level.

In this complicated world it is rare that a political argument can be proved with evidence readily accessible to everyone, but until deregulation the airline industry provided one such case. If you did not believe that the effect of government regulation of transportation was to drive prices up, you could call any reliable travel agent and ask whether all interstate airline fares were the same, how PSA’s fare between San Francisco and Los Angeles compared with the fare charged by the major airlines, and how that fare compared with the fare on other major intercity routes of comparable length. If you do not believe that the ICC and the CAB are on the side of the industries they regulate, figure out why they set minimum as well as maximum fares.

Pete Waterman’s £1 million model railway collection

Filed under: Britain, Media, Railways — Tags: , — Nicholas @ 04:00

Model railways can get expensive, but they don’t normally get into seven figures (and that’s approximately one-tenth of the total value):

Pete Waterman’s indelible links with pop empires and reality television overlook the personal vocal abilities of the mogul himself. In the late 1960s, when his infatuation with trains and their miniature replicas began, he funded his acquisitions by starting the flying choir — a venture in which his singing entertained wedding-goers at different churches across Coventry on Saturdays, earning 10/6 a time.

A guinea a week from his paper round and “five bob” from fetching coal in his sister’s pram also helped him replicate the sights he would witness from the tracks stretching past his childhood home. “When you live in a council house and these things go past your door, it’s your first encounter with beauty,” recalls the man whose collection, according to auctioneers Dreweatts, is of “incalculable” value 56 years in.

“There were people sitting with white tablecloths and table lamps having dinner. It was magical. Think of the contrast: we didn’t even have glass in the windows at home.

“I set out to create the best, and I have done for railways what some people have done for model cars and planes.”

Waterman is about to put £1 million of his scratch-built model trains under the hammer in Mayfair. It’s only a tenth of the full collection, but selling the live steam and 10mm to foot-scale models will raise enough to safeguard his full-size steam engines, held around the country under the direction of the Waterman Railway Heritage Trust.

“These full-size engines won’t be back in steam for ten years,” he admits. “I’m 68 now and this is probably the last chance I will have to restore the engines held by the trust. So I’m making sure there is enough money in ten years’ time to continue the job.”

Besides, he feels the artefacts going on sale are somewhat anomalistic. “They no longer fit into the wider collection. It’s almost like I was into Pre-Raphaelite art and I’m now a modernist.”

It certainly is no big deal to have a small cruise along the canals or ride a train. But what is essential infrastructure today had to be invented out of necessity in the late 18th and early 19th century. In our new episode Brett tells you everything about canals and railways and how they changed the way we transport things.
