Ok, I said I would report this bug, so here it is. The majority of the documentation is in this thread. http://starmadedock.net/threads/rail-turrets-and-walkers-dont-mix.7835/
Basically, when you have a rotation/elevation rail turret mounted on an entity, this happens: When bumped or otherwise moving on its own, the entity just jumps back to it's beginning position. If you mount a rotation only turret, this bug is absent. This happens irrespective of mass.
I have observed similar jumping around on bumped asteroids, but don't see any other reasonable connection between the two phenomena, especially due to the fact that the asteroids did this before the rails update.
Is this bug already known? If not, I will submit a formal bug report.
