Where High Speed Trains can beat short-haul flight

Spain has a new high speed railway (HSR) network that appears to be a huge success, according to the Guardian:

Last year’s drop in air travel, which was also helped by new high-speed lines from Madrid to Valladolid, Segovia and Malaga, marks the beginning of what experts say is a revolution in Spanish travel habits.

In a country where big cities are often more than 500km (300 miles) apart, air travel has ruled supreme for more than 10 years. A year ago aircraft carried 72% of the 4.8 million long-distance passengers who travelled by air or rail. The figure is now down to 60%.

“The numbers will be equal within two years,” said Josep Valls, a professor at the ESADE business school in Barcelona.

Two routes, from Barcelona to Malaga and Seville, opened last week. Lines are also being built to link Madrid with Valencia, Alicante, the Basque country and Galicia. The government has promised to lay 10,000km of high-speed track by 2020 to ensure that 90% of Spaniards live within 30 miles of a station. The prime minister, José Luis Rodríguez Zapatero, boasts it will be Europe’s most extensive high-speed network.

While I’m always skeptical of HSR advocates’ larger-than-life claims, the Spanish system may be in a good position to permanently claim a big share of the short-haul air passenger market. The situation works to the strengths of HSR: relatively dense population corridors, short-to-medium length journeys, and government subsidy of construction costs.

HSR cannot be run on the same tracks as regular freight trains and commuter passenger trains: the signalling, degree of curvature of track, and speed differential between the HSR and ordinary trains creates too many risks. HSR must have its own right of way, which pretty much always means that governments must get involved to condemn existing properties and expropriate them for the benefit of the railway.

That HSR is, or may become, a success in densely populated European countries does not make the case for North American HSR efforts, as I’ve posted a few times before.

Passwords and the average user

In this day of widely publicized panic about online security, it’s time we revisited the basics of password security. I’m sure that none of you reading this would ever have a less-than-ironclad routine for all your online activities:

  1. Never ever use the same password on multiple sites. Once they’ve grabbed for login for the MyLittlePony site, they’re into your bank account . . . or worse, your MyLittlePonyDoesDallas account.
  2. Always use the maximum number of characters allowed . . . I know it’s a pain when a site allows 1024 characters, but your online security is paramount. I believe most health insurance now covers carpal tunnel treatment, so you’re golden.
  3. Never include any word — in any human language — embedded within your password: this includes all the words in the Scrabble® dictionary for every known language. Can’t assume that the black hats speak English, y’know.
  4. Always use both capital and lower-case letters and include at least a single digit and a non-letter character in every password.
  5. Note: Don’t try to be clever and use 1337speak. The folks trying to crack your password all post on 4chan: you’re giving them a head-start. They dream in 1337.

  6. Change your password regularly. Daily, if necessary. Even hourly if you share a computer with others.
  7. Never, ever write your password down. That’s the first thing they’ll look for when they break down your door and trash your crib.
  8. Never, ever re-use a password. Don’t pretend you haven’t done this one. We all used to do it, until site admins started checking that you hadn’t re-used an old password.

Of course, even the professionals don’t do all of this. Some of ’em don’t do any of it. Do like the pros do: set all your passwords to “passw0rd”. Nobody ever guesses that.

Chip Scoggins and Chris Miller poke a little fun at both the birthday boy and his former team:

FAMOUS OCT. 10 BIRTHDAYS

Guiseppe Verdi (1813) Refused to retire. Died at age 87. Composed romantic operas, none set in Green Bay.

Thelonious Monk (1917) The great jazz pianist retired when he was 54. Packers fans preferred accordion players.

Tanya Tucker (1958) The country singer’s “Two Sparrows in a Hurricane” is interpreted by some as Favre’s ode to Ted Thompson and Mike McCarthy.
