While passing a failed equipment detector, what action is required?

When passing a failed equipment detector, the appropriate action is to reduce train speed to no more than 30 MPH. This requirement is in place to enhance safety and ensure that any potential issues with the train can be addressed without further exacerbating the situation.

A failed equipment detector typically indicates that there may be a problem with the train or its components that could affect safe operations, such as issues with the wheels, brakes, or other critical parts. Reducing speed allows for safer maneuvering through the detection area and ensures that the train crew has enough time to respond to any unforeseen circumstances.

Options suggesting an increase in speed or stopping immediately may compromise safety further. An immediate stop could create hazards for following trains or lead to other operational complications. Calling for maintenance is a prudent action but is not the immediate response required while passing the detector. Instead, the priority lies in controlling the train's speed first to maintain safety.
