What is the ordinary speed on open track with no restrictions?

• A. The maximum permitted speed for the track
• B. The fastest allowable speed on the line
• C. The standard operating speed established for the track class or route
• D. The speed limit posted at the nearest signal.

Answer: (C)

Ordinary speed is the standard operating speed assigned to a track class or route for normal, unrestricted running. It’s the baseline NORAC defines for routine operation when conditions are typical and there are no signals or other restrictions requiring a slower pace. It isn’t the maximum permitted speed, nor necessarily the speed shown at a signal, and it isn’t just the fastest allowable speed on the line—the ordinary speed is the normal pace established specifically for that track, used unless a restriction dictates otherwise.
