What does the term “mechanical failure” refer to in switch operations?

In switch operations, the term “mechanical failure” specifically pertains to a breakdown or malfunction in the physical components of the switch itself. This can include issues with the switch mechanism, such as components that may be worn out, broken, or otherwise unable to function properly, which can hinder the proper alignment and operation of the switch.

Understanding mechanical failures is crucial for ensuring the safety and efficiency of rail operations, as these failures can lead to derailments or impede the movement of trains if not addressed promptly. This distinguishes mechanical failures from other operational issues, such as faults in signaling systems, train scheduling delays, or reductions in train speeds, which do not directly involve the physical mechanisms of the switch.
