Gentelmen,
I recently faced very important issue within the game, how actually to change train vehicle without damaging supply chain (cargo lines). I've been searching all the known train fever communities for me and haven't found any suitable solution.
The problem is that route to a depot takes some time, which makes supply factories wait (the issue is noticeable in the beginning of a game when locomotives are slow, especially if you have only one train on this line), after such a small brake factories tend to decrease production, and sometimes dramatically.
Is there any way how to add new carriages for example, without affecting factories' production?
Thanks in advance for replies
