Ghost trains should occupy signals

[DeadMG]

TL;DR
A ghost train should turn a signal red just like a real train

What?
Existing, real trains cannot enter blocks which have ghost trains in them.

Why?
Currently, placing ghost trains on tracks which are in use is pretty dodgy. Because the ghost train doesn't block the signal, you can get a lot of weird interactions. For example, the robots can place half of the new train right after the real train decided to enter that block at full speed, annihilating it. Then the other robots place the other half the train after the real train leaves.

Yeap. That is exactly the reason I have dedicated train-building areas. That have no way for trains to get into them.

But you could, like, start the ghost train on an exit-only siding instead of right in the middle of things.
