Rule 576 — Switching at a Controlled Location

1. (a)Signal Indication - The preferred method of switching at a controlled location is with the use of the signal system by having the RTC signal the train or transfer over the controlled location with directional signals. If unable to clear the controlled location when switching is completed, the RTC will authorize departure by issuing a Rule 566 or 577 to the train or transfer. If the first move into the block was authorized by Rule 564, operation to the next signal must be made at RESTRICTED speed. Rule 566 or 577 would not be required when the RTC verbally authorizes the train or transfer to pull ahead to the next signal where there are no dual control switches to be encountered.
2. (b)Switching Signals - A member of the crew will request the switching signal so that multiple moves may be made through the controlled location on a specific route. When switching is completed, the RTC must be advised to ensure the signal will be cancelled. Before doing so, the member of the crew requesting the cancellation must advise all other crew members and receive their assurance that they are and will remain clear of the switching signal limits. If unable to clear the controlled location, the RTC will verbally authorize departure. The RTC will then cancel the switching signal. The train or transfer may then proceed to the next signal at RESTRICTED speed. To avoid having to proceed at RESTRICTED speed, trains or transfers should attempt to back clear of the switching signal on the final move and leave on a more permissive signal indication.
3. (c)Rule 566.1 and 577.1 Signals Suspended - The train or transfer must be authorized to enter the block before Rule 566/566.1 or 577/577.1 authority is issued by the RTC . If the train or transfer is unable to be clear of the limits when switching is completed, they must advise the RTC before leaving the location. If Rule 564 authorized the first move into the block, the train or transfer must operate to the next signal at RESTRICTED speed.
4. (d)Taking Head-Room - Provided that the trailing end remains within non-main track territory, a train or transfer may accept a signal to enter a controlled location, where the intent of the move is to subsequently reverse direction so as to be completely in the clear in the non-main track territory. The RTC must be informed of the intended head-room move when the signal is requested. The crew may request one or more head-room moves but each time the signal provides a permissive indication, it is for one head-room move only.
