When can a train operator accept a route from express to local track?

Accepting a route from express to local track is permissible when the local route does not divert the train from its scheduled line. This ensures that the train remains on its intended path and adheres to the overall scheduling of the service.

Making such a transition without diverting from the scheduled route helps maintain operational efficiency and minimizes disruption to other trains and services on the network. It allows the train operator to make the switch smoothly while aligning with set schedules and ensuring safety protocols are followed.

Other scenarios, such as being instructed by the conductor or there being no passengers on board, do not necessarily correlate with the operational rules regarding route acceptance. Additionally, running behind schedule doesn't justify changing from express to local unless it aligns with maintaining the scheduled path. Thus, the crucial factor is that the local route must not cause deviation from the schedule, making this the right condition for accepting the change.
