A number plated signal displays a red aspect. How must your train proceed past the signal and when do you resume speed?

• A. Restricted speed until leading wheels have passed the next governing signal or the end of the block system
• B. Stop and wait for clearance
• C. Proceed at 60 mph
• D. Maintain speed until next signal

Answer: (A)

When a red signal has a number plate, you’re allowed to pass it, but only at restricted speed. This means you must slow down to a speed that lets you stop within the distance you can see ahead and within the block, staying prepared for any approach or obstruction. You keep moving at that restricted speed until the train’s leading wheels have cleared the next governing signal or reach the end of the block. At that moment you may resume normal speed. The other options would require stopping completely or speeding up, which isn’t permitted under a red signal with a speed plate.
