How does the train work?
How Does An Electric Locomotive Work:
Electric locomotives use electricity from overhead wires to convert electrical energy into mechanical energy, making them lighter, faster, and quieter than steam or diesel engines.


How Does a Diesel Locomotive Work:
Diesel-electric locomotives provide cheaper upfront costs and improved reliability.

Train wheels are conical, allowing them to travel a longer distance while turning at the same speed as the inner wheel. The wheel on the left is positioned further out from the center of the axle than the right, which is beneficial for stability and comfort of the passengers. Railways have wide curves due to the "flange" of the wheel limiting lateral movement. Distance between tracks must be greater than wheel flanges to allow wheels to move laterally in curves, reducing efficiency and comfort. The "nominal gauge" of a railway is defined for the straight section and widened in curves to allow the train to tilt.
