Rule 513 — Entering Main Track

1. (a)Before entering or fouling a main track and no movement is observed approaching on the main track, a crew member must reverse the switch and wait five minutes, unless a greater period is specified in special instructions before allowing the movement to move foul of the main track. The crew member must remain at the switch until the movement has entered the track. The switch must be quickly restored to its normal position should an approaching movement on the main track become evident. When entry is to be made through a crossover, the switch in the track on which the movement is standing is the only crossover switch to be reversed for the required waiting period. EXCEPTION: The required waiting period need not be observed within cautionary limits or when: Before relieving a crew, the RTC must ensure that there are no movements operating in the block that will approach the switch. The switch must be opened within 5 minutes after receiving permission from the RTC .
2. (b)A movement entering a block between signals, must move at RESTRICTED speed to the next signal, unless or until the track is seen to be clear to the next signal and the indication of such signal permits movement at other than RESTRICTED speed.
