Corruption of public transport nodes did not happen even once during my tests, The issue seems to occur so randomly and seldomly that it seems impossible to reproduce/track it down to a specific cause.

Unfortunately I was unable to reproduce your problem in ~8 hours of gameplay with multiple save and load actions.
