An on board unit (OBU) of a train may determine that a trip or shift has ended and may initiate a train log-off procedure. The OBU may monitor for at least one alert condition during performance of the log-off procedure, the at least one alert condition comprising a condition wherein unauthorized train movement is possible. In response to detecting the at least one alert condition, the OBU may report the at least one alert condition and disable the train log-off procedure until the OBU determines that the at least one alert condition is resolved. In response to failing to detect the at least one alert condition and/or in response to determining that the at least one alert condition is resolved, the OBU may complete the train log-off procedure.
