Train management for personal transportation with some new concepts.
Mods introducing new content into the game.
Trains are great, but what if they could do even more?
I believe electric shuttle batteries ought to be much larger. It's very easy for them to run out of energy on long journeys, or when returning from long journeys.
Alternatively, could they perhaps be made to charge while driving if there's energy?
I am sorry but I have no idea what you mean. The modules that go into the trains do not use electricity.
