Trains bugging out and unable to interact after collision

I've been playing around with some trains in my modpack and encountered this issue where after two of my trains collided, they glitch out and appear to fly across the map. The entities on the train seem to stay where the train should be, and I can't interact with the trains themselves either where they should be or where they appear, which also means I can't recover the trains in any way. Anyone know what could be causing this? Main relevant mods are of course SnR (1.6.3, forge) and possibly extended bogies (0.5.10).
