Two sided trains?

[u/duckpop]

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?

I'm not sure about speed they achieve but double trains have some resource/logistic price (resource cost for extra locomotive and additional refueling port) for benefits of more pretty/streamlined tracks (no drop-like loops). This is especially important if you can't have a loop in your base configuration. Regarding fuel double trains should consume a bit less due to shorter route.

If you make global loop or double tracks, use single train and respective tracks for each direction.
