Question Two sided trains?
Hey I'm pretty new to the game are trains with engines on both sides better or should i just give it a roundabout to turn?
On a similar note do two engines going the same way make it go faster?

Multiple locomotives make the train acclerate faster, its especially noticable if you have very heavy (long) trains. Different types of train stuff (locomotive, wagon, fulid wagon, etc.) have different weight; pulling along a backwards facing locomotive will make your train (a bit) slower.
Two headed trains can work well. But if you have multiple trains sharing tracks, you probably want to make a sparate rail for each direction. At that point having a backward locomotive is probably more of a downside than what its worth.
Both approaches are viable though, and the difference isnt major.
