CN experiments with natural gas for its locomotives

Canadian National Railways is running a limited experiment with a pair of retro-fitted diesel locomotives converted to running on natural gas:

Canadian National Railway is exploring whether its feasible to use cheap and relatively clean natural gas to power its trains instead of diesel.

CN has retrofitted two of its existing diesel-fired locomotives to run mainly on natural gas. It’s testing the locomotives along the 480-kilometre stretch between Edmonton, a key energy processing and pipeline hub, and the oilsands epicentre of Fort McMurray, Alta.

Longer term, CN and three other partners are looking at developing an all-new natural gas locomotive engine as well as a specialized tank car to carry the fuel.

The increasing length of freight trains in Canada

Some eye-opening statistics on the length of freight trains being run by Canadian National (CN) and Canadian Pacific (CP) these days:

Transport Canada launched a six-part study into the long-train strategies at the country’s largest railways this month with an eye on developing policies for how these longer, heavier trains are assembled and run. The goal of the two-year study is to develop science-based regulations that will hopefully reduce the number of derailments in the country.

Despite the concern from regulators, these longer, heavier trains in recent years have been a godsend for North American railways, which swear by their safety. Not only do they improve the efficiency of the rails by reducing the number of trains required to transport goods, but they in turn reduce the crews needed and the fuel used to move their shipments.

If properly built, they can also reduce wear and tear on the trains and the tracks themselves by cutting down on in-train forces, lowering maintenance costs substantially over time.

The cynic in my asks why, if CN (for example) actually managed to reduce the number of rail accidents to an all-time low last year, the regulators are now launching the investigation. Fewer accidents now equals a point of serious concern on the part of the regulators? Why?

Up until the 1990s, the average freight train in Canada was about 5,000 feet (1.54 kilometres) long and weighed 7,000 tons. But it is now not uncommon to see these trains stretch to 12,000 feet, sometimes as much as 14,000 feet (more than four kilometres), weighing up to 18,000 tons.

While CN is comfortable sticking with the size of its longest trains now, about 12,000 feet, CP continues to push the boundaries of how long it can build its trains by developing some of the industry’s most cutting-edge technology in recent years to help it do so.

The benefits are clear. CP estimates, for example, that the labour costs alone on a typical transcontinental train are now 30% lower than they would be if it was using smaller trains.

So, the trains are longer, carry far more freight, cost less to run, and customers are happy. The government must act!
