While the average car engine has about 200 horsepower, locomotive engines typically range from 2,000 to 4,500 horsepower. Train operators rely on diesel power across the full range of rail power applications.

Of that, each loaded car weighs 143 tons apiece with 100 tons of coal in each car. This is exclusive of each locomotive that could weigh up to 415,000 pounds apiece. Depending upon the daily fluctuations of coal as a commodity, the value of the coal itself could reach as high of upwards of $1 to $1.6 million per train.
The giant two-stroke, turbocharged engine and electrical generator provide the huge amount of power needed to pull heavy loads at high speeds. Cummins' locomotive engine weighs over 24,000 pounds (10,886 kilograms). The generator and electric motors add more mass on top of that.
In the USA, staff were instructed to lock toilets when the train was stopped in a station and unlock them when the train was again underway. Mercifully, new trains no longer dump waste on the tracks. Instead, trains are fitted with chemical holding tanks.
Neither the conductor nor the engineer is allowed to sleep on the train. They must be awake and alert throughout their entire shift. So, where do they sleep? After their shift, conductors and engineers sleep either at home or in a motel at an away terminal.
While modern trains won't litter the tracks with human excrement, the traditional method did just that. This is what was known as a hopper toilet. It could either be a simple hole in the floor (also known as a drop chute toilet) or a full-flush system.
The life expectancy of diesel-electric and electric locomotives is expected to be similar—about 25 years. Both types of motive power are subject to technological obsolescence.
rather than pay for the expense of maintaining track to a higher standard, and having to maintain the additional cab signals, and having to outfit all locomotives that use the line with cab signals, or ATS, or ATC, the freight RRs simply place the speed limit at 79 mph, and use Automatic Block signal systems.
Freight and passenger rail rely almost exclusively on diesel power. The latest diesel innovations contribute to cleaner air and reaching climate goals. According to the Association of American Railroads, in a typical year, US freight railroads move around 1.7 billion tons across nearly 140,000-miles of track.
