Push buttons contained in a box located adjacent to a signal used to request or cancel a route are called what?

• A. Route Selector
• B. Red Tag
• C. Right-of-Way
• D. Procedures

Answer: (A)

In rail operations, the device with push buttons next to a signal used to request or cancel a path is called the route selector. It lets the operator specify which route the train should take through the interlocking, triggering the appropriate switches and signal settings. Pressing the appropriate button requests that route; if the route is safe, the interlocking allows the signal to show a proceed aspect. Cancelling a previously requested route is done through the same controls, reversing the setup as needed. The other terms don’t describe a control panel used to set or cancel a route: a Red Tag is a safety tag for track work, Right-of-Way refers to priority of movement, and Procedures are general guidelines, not the hardware you push to pick a route.
