[0.17.46] Crash when removing tracks with signals while train passing by

[Mhal007]

What did I do and what happened:
Copied tracks that are now visible in the screenshot in a to-remove state.
Pasted it on the right side of the screenshot.
Marked tracks to be removed with the deconstruction planner (alt+d)
Just before I released the mouse button, a train went right into the area that I was about to deconstruct, which resulted in marking the train to be deconstructed as well (not sure if that's important)
Approximately half a second passed (didn't do anything in the meantime), the train continued moving, so that's why it's partially out of the original deconstructing area, and then the crash happened.

The steps to reproduce probably include trying to deconstruct an area with tracks and signals while train is passing by.
It happened the first time for me.

I have attached two last autosaves, and also all log-like files that I've found. It's probably too much but didn't want to send too few. Let me know if you'd need something more as I have backup-ed the entire .../Roaming/Factorio folder just in case.
