6.27 Movement at restricted speed
When required to move at restricted speed, movement must be made at a speed at a speed that allows stopping within half the range of vision short of: Train, Engine, Railroad Car, Men or equipment fouling the track, Stop signal, Derail or switch lined improperly When a train or engine is required to move at restricted speed the crew must keep a lookout for broken rail and not exceed 20 MPH. Comply with these requirements until the leading wheels reach a point where the movement at restricted speed is no longer required. |
