Why is there an engine at the end of a train?

One of the primary reasons railroads use distributed power is to increase the pulling power of the trains as the length and weight also increases. By placing additional locomotives in the middle or at the end, the overall pulling power of the multiple locomotives increases, moving the train efficiently and effectively.

Yes, locomotive engines typically have a toilet, also known as a lavatory or restroom, for the use of the crew members who operate the train.

As wireless technologies advanced in the 1960s, freight railroads began adding extra locomotives to the rear of trains to give them enough power to climb steep hills. This is how distributed power was born.

For the most part, it doesn't matter which way a modern locomotive faces, it works just fine either way. Typically though, the main reason some locomotives will be facing backwards is because turning trains is not always easy. In the past, you would need a wye, loop, or turntable to turn a train/locomotive around.

Pulling loaded coal cars? Once the train is rolling, an engine with 110,000 lb tractive effort should be able to maintain 11-12 mph with at least 200 cars-- maybe 300 or more.

When a train hits a car or truck at a crossing, the train always “wins”. It is much, much larger and heavier than any truck. However, it is possible that a collision at a “grade crossing” (where a road crosses a track at track level, not an overpass or underpass) can cause a locomotive to derail.

On curved sections, the longitudinal (traction or braking) forces between vehicles have a component inward or outward respectively on the curve. In extreme situations these lateral forces may be enough to produce derailment. A special case of train handling problems is overspeed on sharp curves.

Why do trains sound their horn? Federal law requires the train crew when approaching a road crossing to sound the horn at all public crossings for the protection and safety of motorists and pedestrians regardless of whether crossings with gates and lights are present.

As a train slows down on steep grades and tight curves, or approaches a signal light or stopping destination, sanding assists in preventing the wheels from sliding as the braking systems are applied. Sanding has been used to increase friction and improve traction since the very inception of railroad transport.

If the train is heading in the direction in which the locomotive end of the train is facing, this is considered 'pulling'. If the train is heading in the opposite direction, this is considered 'pushing' and the motorman or engine driver is located in the alternative cab.
