If a train loses its air while entering a station in Bypass, what should be done?

When a train loses its air while entering a station in Bypass, notifying the Trainmaster and refraining from pressing the door enabler is the appropriate course of action. This situation indicates a potentially dangerous condition that should be addressed by a qualified personnel. The Trainmaster is responsible for managing operations and ensuring safety protocols are enacted, which makes it imperative to inform them of the situation.

Pressing the door enabler under such circumstances could lead to doors opening in an unsafe manner or while the train is not fully secured, which could pose a risk to passengers and staff. Following established communication protocols allows for a coordinated response to the situation, ultimately ensuring the safety of everyone involved.

While other actions, such as activating emergency brakes or notifying passengers, may seem reasonable, they could interfere with the proper emergency protocols or lead to confusion without clear instructions from the Trainmaster. Thus, the decision to notify the Trainmaster first keeps the safety protocol intact and allows for appropriate measures to be taken.
