@Caligrad06 Train length isn't the issue I have almost a dozen trains in my save that are this long. Most likely you have nodes too close in some places of your city which can cause cars to float. On the poi t of backing up traffic, I made these trains to be realistic length so the best way to utilize them is on a more realistic style railroad layout.

It messes up the game. The train is tooooo long so it backs up the rail traffic and the train floats through the air sometimes. Needs to be tweeked because i noticed an increase in flying cars after i downloaded this. .

This is verry beautiful~ although I didn't subscribe it
