Steam Train Railroad

So I've built a steam train railroad with four stations in my park. I've added four separate trains so people won't have to wait too long between departures. The problem is that because there are slight differences in track length between stations, that means one train might arrive a few seconds later then the others, and therefor it departs a few seconds later than the others. Over time this cause all four trains to queue up at one station. My question is this: Is there a way to synchronise departures, so the trains always leave the station at the same time as the others?
Afraid not possible to sync stations at the moment. Ni idea if it will be implemented at some point.
