Why train engines are not turned off?

Trains, due to their size and weight, require the highest possible brake line pressure in order to stop efficiently. For obvious reasons, loco pilots never make any concessions when it comes to brake line pressure. Another reason for not shutting off diesel train engines is that the engine itself is quite efficient and reliable.

Are steam locomotives more powerful than diesel?

Because diesel engines have such high thermal efficiency (modern diesel engines achieve 45 percent efficiency compared to a steam engine’s 10% efficiency), they can travel longer distance between refueling stops than other types of engines. This allows them to travel longer distances between refueling stops.

Why do locomotives run back to back?

According to Jacobs, Union Pacific diesel locomotives are bidirectional, which means that they generate the same amount of power when driving in reverse as they do when traveling in the other way. The direction in which the locomotive travels makes little difference in terms of efficiency or safety.
