What must the engineer do if they encounter an improper short station stop in MCS mode?

When an engineer encounters an improper short station stop in MCS mode, the appropriate action is to pull forward to make a correct stop. This is necessary because making a proper station stop ensures that doors align correctly with the platform, allowing for safe and efficient boarding and alighting of passengers. Pulling forward helps to position the train accurately and promptly caters to the operational schedule and safety standards set by PATH.

While other actions such as conducting a safety check, contacting central control, or waiting for the Trainmaster’s instructions may come into play during various operational issues, the immediate need to correct an improper stop is prioritized by physically moving the train to the designated position at the station. This action minimizes inconvenience for passengers and maintains the flow of train schedules.
