What must a TEC train do during meets with other trains?

In the context of train operations, when a TEC (Timing and Efficiency Control) train encounters other trains, it is essential for it to hold the main track. This is a critical aspect of train dispatching because the main track is typically the primary line for train operations, and holding it ensures that the TEC train maintains its schedule and operational efficiency.

By holding the main track, the TEC train also helps to prevent unnecessary delays that could arise from switching to a siding or stopping. This allows for better traffic flow and minimizes the risk of congestion on the rail network. Maintaining position on the main track while other trains pass ensures that safety and efficiency are prioritized during meets, aligning with the overall operational protocols of train dispatching.

Other options, such as yielding to passing trains or stopping until given permission to proceed, might introduce inefficiencies or complications in certain operations. Changing to a siding track could vary based on specific circumstances concerning the type and priority of the train, but in general, holding the main track is the preferred action in scheduled operations involving TEC trains during meets.
