Server crash (null pointer exception related to track kit (locking)

Description of the Bug
The server crashes out of the blue with a null pointer exception. Says related to locking track kit.
Before the crash, I received a WALL of red text in the server command line that seems railcraft-related. There was so much that it scrolled my terminal window... whatever was last left is there.

Additional context
Add any other context about the problem here.
I'm trying to recreate... I have 8 trains in the exact situation. I am watching the area it happened though. i'll let it run up to 10 trains in this situation (the rail network automatically spaces the trains out through the network).
What happened was that some cart seemed to get disconnected from a train... this was stuck in another entity... i think it caused some feedback to railcraft or other trains...
I restarted the server (it crashed), then i had another train get stuck there... I stopped the train, and tried to troubleshoot.. there was an invisible cart there. restarted the server again. now I could see the cart. broke it, reset the train that was stuck, and it was fixed... but I don't know what caused the initial lockup (should not have been trains crashing... they were all spaced)
Another crash. In creative was trying to click on a cart to delete. Sometimes the click goes through to the next block. This click landed on a turnout track, (removing it?) and instantly crashing the server.

Yeah. I am trying to add some context for you, not sure if it helps you troubleshoot. Here is another crash. Was trying to delete a cart. INstantly crashed server. You don't have to read... same as above.
