The short answer is that for the majority of the diesel era, one manufacturer was dominant, EMD. Thousands of single models of EMD locomotives were purchased, and these sale eclipsed the combined totals of all other manufacturers.

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.
CLIMATEWIRE | The first U.S.-made high-speed bullet trains will start running as early as 2024 between Boston, New York and Washington, with the promise of cutting transportation emissions by attracting new rail passengers who now drive or fly.
Japan: L0 Series Maglev (374 mph)Although not yet in regular service, this Japanese train, which is currently being developed and tested by the Central Japan Railway Company (JR Central), holds the land speed record for rail vehicles, clocking in at 374 mph.
American railways were also built on a wider gauge (the distance between the rails), which allows for larger and heavier trains. As a result, American freight railways are much more efficient than their European counterparts, carrying almost three times as much cargo per mile of track.
What's faster than a speeding bullet, a phrase used to describe Superman? The new Shinkansen, or Japanese bullet train. Japan Rail announced the design of a magnetic levitation train that will achieve speeds over 600 kilometers per hour (374 miles per hour), or 1 mile (1.5km) every 10 seconds.
The sole long-distance intercity passenger railroad in the continental U.S. is Amtrak, and multiple current commuter rail systems provide regional intercity services such as New York-New Haven, and Stockton-San Jose. In Alaska, intercity service is provided by Alaska Railroad instead of Amtrak.
The new Acela will operate at top speeds of 160 mph vs. today's fleet, which operates at top speeds of 150 mph. Amtrak's new Acela fleet is scheduled to enter service on the NEC in 2024.
The diesel engine drives an alternator, which produces electricity to run electric motors mounted on the locomotive's axles. The internal combustion engine was a dramatic improvement in efficiency over the steam locomotive, making substantial savings possible in maintenance and the elimination of widespread facilities.
The horn alerts people that a train is approaching a railroad crossing. It can also be used to warn animals or trespassers in our right-of-way along a section of track. Many people don't realize that federal and state regulations require us to sound the horn whenever we approach any crossing.
Railroads govern the use of bells on locomotives and mandate when they should be rung, as at crossings, quiet zones, or meeting points. Locomotive bells' chief function is to warn pedestrians, crew, or others nearby with a bright ding that a train is moving or will be soon.
Because most tracks are optimized for heavy fright trains which in America are more important, economically, than passenger transportation. Heavy trains displace tracks, sleepers and ballast so that it is impossible to let locomotives and passenger wagons run with higher speeds. And fright trains are slow.
Why are American train platforms so low? Largely to provide clearance to freight cars, which can often be over-wide. If you're at a “passenger train only” facility like Penn Station in New York, then the platforms are at the same level as the train exits.
The erstwhile Great Indian Peninsula Railway introduced a broad gauge of 1,676 mm (5 ft 6 in) for the first passenger railway line in India, between Bori Bunder and Thane. This was later adopted as the standard throughout the country, as it was thought to be safer in areas prone to cyclones and flooding.
Maglev trains work on the principle of magnetic repulsion between the cars and the track. The word maglev is actually a combination of the words “magnetic” and “levitation.” The magnetic levitation, or floating of the train, is achieved through the use of an electrodynamic suspension system, or EDS.
Over 2,800 pairs of bullet trains numbered by G, D or C run daily connecting over 550 cities in China and covering 33 of the country's 34 provinces. Beijing-Shanghai high speed train link the two megacities 1,318 km (819 mi) away in just 4.5 hours.

High-speed rail in the United Kingdom is provided on five upgraded railway lines running at top speeds of 125 mph (200 km/h) and one purpose-built high-speed line reaching 186 mph (300 km/h).
