That is a good question. For a simple design, all you need is for the train to go backwards and forwards. But simple isn't the objective of this thread. To make a turn, perhaps modifying the part that keeps it on the rail(s)? It cannot have two of them if it turns, making it vulnerable to tilting, and with the freedom to go in any direction that will make it even more vulnerable.

If you sacrifice the "rail" aspect and instead have it as a free cart, but with barriers on the edge to prevent it from going in the wrong direction, that could work. It is still a train, with exactly the same usability. Functionally, it would be identical.

However, freestanding monorails and duel-rails look epic with a train attached. So a solution would be ideal.
