anon (01/09/2016) [-] The direction a train travels in is based on its front. If that weren't the case, trains would constantly be traveling 2-3 directions at once all the time, making this not-so-neat.
You would never say that a train is traveling both north-west and south at the same time. It's instead traveling north-west.
If there is no specified front that is constantly changing direction, as is the case here, then instead the updating attribute falls onto the cargo carts, and which cargo cart is the "front" at any given time is constantly changing instead, with such a cart's direction never actually changing.
I'm fun at parties. Here's my number.

kafudamapla (01/09/2016) [-] What is "bi-directional"? It's just doing what any figure-8 track does, albeit with more twists and the train is continuous. It's pretty, but I don't see what's so interesting
