The blue light stations house switches that perform which action at the affected station?

• A. Shutdown power from both sides of the guideway
• B. Activate emergency brakes
• C. Open track switches
• D. Switch to backup power

Answer: (A)

Blue light stations are built to quickly isolate a section of the guideway for safety. The switches at the affected station are designed to shut down traction power on both approaches, creating a dead zone where responders can work without the risk of an approaching trolley or train moving into the area. This power isolation is the essential safety action, rather than braking or re-routing trains. Activating emergency brakes is a separate safety function tied to the train itself, opening track switches would change which way a train could go but wouldn’t safely de-energize the area, and switching to backup power would keep power on, which defeats the safety purpose of isolating the section.
