Why are American steam trains so big?

European railways have tighter curves and the tunnels and bridges have smaller clearances. Likewise, American locomotives are longer, taller, and wider than their European counterparts. The American locomotives have much greater distances to travel, and are pulling much heavier trains than their European counterparts.

As a consequence, locomotives built in the United States early developed sets of leading wheels for locomotives that would make them less likely to derail, and because of the steeper grades, particularly out west, U. S. engineers created increasingly larger locomotives, eventually producing giant articulated ...

The size (dimensions) is determined by the loading gauge, and the US railroads have a considerable wider and higher loading gauge than UIC, and even more so than the Brits. The simple answer is that everything is bigger in the USA!

The efficiency of longer trains is why the big Class 1 (“big railroads”- CSX, UP, BNSF, etc. ) railroads like to run as many long freights as possible and tend to spin of low traffic rail segments to shortlines (“little railroads”) with less overhead who can earn money with the shorter trains.

A story of US transportation Highways (as well as aviation) became the focus of infrastructure spending, at the expense of rail. This trend has continued, and not the least because highways require continuous maintenance, while the US's growing population demands more lanes and roads to relieve congestion.

Tracks: None of the nation's rail lines are built for trains to run 200 mph. Amtrak's Northeast Corridor — the busiest intercity U.S. passenger route by a wide margin — is filled with sharp curves, bottlenecks, decaying tunnels, bridges and overhead power lines that slow down trains.

Second, whereas American locomotives were covered with exposed piping, compressors, and various mechanical devices, British steam engines generally had all these things hidden under a smooth housing, which, furthermore, was often painted in bright colors — green, yellow, red, blue, or even lilac and bright white, as in ...

In addition, the tracks, signals, rail cars and software made in the U.S. are costlier than imports, largely because the government has not funded rail the way European and Asian countries have, experts say.

Rail systems are so popular in Europe because they can get loads of passengers to their respective destinations en masse — with much less of an impact on the environment. National governments, looking to reduce carbon emissions and put pro-environmental policy into practice, subsidize or own entire rail networks.

Essentially it has to do with history. Rail tunnels in the uk vary in sizes due to different builders and standards throughout history. This means that their loading gauge (how high off the tracks) needs to fit these tunnels.

High-speed trains are European-standard high-speed inter-city trains, capable of typical ground speeds of 250 kph (or 155 mph). They currently run between Moscow, St. Petersburg, Helsinki, and Nizhny Novgorod. These trains are called Sapsan within Russia, or Alstom on the Helsinki – St.
