In the event of a blockade, what should an express train do when routed to local tracks without specific instructions?

In the context of train operations during a blockade, when an express train is routed to local tracks without specific instructions, it should stop at express stations only. This approach is essential for several reasons.

Express trains are designed to operate with fewer stops, typically only at key express stations. When routed to local tracks due to unforeseen circumstances like a blockade, the primary goal is to minimize disruption while providing some level of service. Stopping at express stations keeps the train on its intended route as much as possible, allowing passengers who are expecting service at those locations to disembark and ensuring that operations remain somewhat aligned with regular scheduling.

Stopping at all stations would not align with the express nature of the service and could lead to significant delays, impacting both the train's schedule and potentially the schedules of other trains. Continuing to express stations means the train remains efficient while fulfilling part of its duty to passengers. Proceeding without stopping would not serve any passengers and could also exacerbate delays for those waiting at express stations.

Ultimately, the proper response for the train operator in this scenario balances the need for operational efficiency with maintaining a commitment to providing service at designated stations.
