What happens if the reverse switch is not set correctly when using the Emergency Pipe?

When the reverse switch is not set correctly while using the Emergency Pipe, the Emergency Pipe will not charge. This is because the charging process of the Emergency Pipe requires the correct switch setting to ensure that the proper connections are made for air flow. If the switch is in the wrong position, the system cannot draw the necessary air pressure to operate effectively.

In the context of railway operations, the Emergency Pipe is essential for ensuring that brakes can be effectively activated in situations of emergency or system failure. Thus, a failure to charge the Emergency Pipe means that the emergency braking system might not function, leading to potentially unsafe conditions. It emphasizes the crucial nature of properly configuring all related systems before attempting to engage emergency protocols.
