Which term describes the push buttons used to request or cancel a route?

• A. Route Selector
• B. Route
• C. Panic Brake
• D. Red Tag

Answer: (A)

The push buttons used to request or cancel a route are called route selector controls. In rail operations, a route is the set of track switches and signals that must be aligned for a train to travel along a safe path through an area. The route selector is the control the operator (or the system) uses to request that specific path be established. Pressing it tells the interlocking to lock in the required switches and signals for that route, and cancelling uses the same controls to release or change the request if the path is no longer needed. The other options don’t fit because a route is the actual path, a panic brake is an emergency stop mechanism, and a red tag is a maintenance tag, not the control to request or cancel a route.
