Generally speaking a train crew cannot touch anything to do with a crossing unless there is an emergency. Even then the signal cabinets are locked and would require a signal maimtainer to open them. In most industrial areas they have the bonds almost on top of the crossings. There are usally TOP signs posted at the bond andthe crews must stop and wait for 15 20 seconds before entering the crossing. The old rule use to say " suffecient" which was open for interpretation.
