How will MW equipment proceed at an automatic interlocking not equipped with a MW release box if the equipment does not shunt the track?

When maintenance of way (MW) equipment approaches an automatic interlocking that lacks a maintenance-of-way release box and the equipment fails to shunt the track, the proper procedure is to come to a complete stop until the track is clear. This rule emerges from safety protocols designed to ensure that MW operations do not interfere with train movements and that the equipment does not inadvertently enter a signal indication that could result in a collision or other dangerous situations.

Stopping ensures that the equipment remains in a safe position and cannot unintentionally proceed into a potentially hazardous crossing where other trains may be moving. By waiting until the track is clear, the personnel operating the equipment can visually confirm that no conflicting movements are occurring and that it is safe to proceed.

Other options suggest movement in various capacities, but each introduces unnecessary risk in a scenario where signals are not displayed and the equipment does not behave as expected. Therefore, coming to a complete stop ensures safety and compliance with railroad operational protocols.
