    So, in Unity, Wheel Colliders are primarily used in car/racing games. But, how do you make Wheel Colliders work on a train? This goes for both driving and braking. Any help and suggestions would be much appreciated. Thanks!

    Probably best not to use the physics engine to simulate a flanged wheel.

    I want my game to use real train physics. If not the physics engine, any idea on how I should go upon doing collision?

    Use bezier curves and apply your own physics calculations. Wheel colliders are for suspension and wheel slip. Not that relevant to a flanged wheel on a rail.

    You train wont need to travel on the rough ground like offload truck.
    Therefore, train simulation do not requires wheel physics. You wont need suspension. And if you really want some "shaking", you can really script it in many ways.
    Trying apply right physics to many wheels, will make you more headache.
