Which item is NOT provided by a cab signaling system?

• A. Real-time information on signal aspects, speed restrictions, and route status.
• B. Weather conditions affecting the train.
• C. Movement directions for trains on other tracks.
• D. Passenger seating assignments.

Answer: (B)

Cab signaling is about delivering to the train crew the information they need to move safely along the route: the current signal aspect, any speed restrictions, and the status of the route or interlocking ahead. This system translates track signals into data the engineer can act on in real time, so the train knows exactly how it’s allowed to proceed. Weather conditions, on the other hand, are external factors not encoded into cab signals. They come from meteorological sources or separate onboard sensors and are used for planning and awareness, not as the operational movement authority shown in the cab. Passenger seating assignments are unrelated to how a train is signaled or moved. Directions for trains on other tracks are typically handled by dispatch or central control to coordinate traffic, not by the cab signaling data presented to a single train.
