Grand Scales General Code of Operating Rules – First Edition – January 1, 2007
Restricted Until Next Clear Signal 8.10 When a train passes a signal requiring movement at restricted speed, the train must move at restricted speed until its leading wheels have passed the next governing signal or the end of the block system, unless given proper authority.
Stop Indications 8.11At a signal displaying a stop indication, and if no conflicting movement is evident, the train will be governed as follows:
a crew member must immediately contact the control operator unless the train is:
within track and time limits or
entering track and time limits from any point other than either end of track and time limits.
before authorizing the train to proceed, the control operator must know that the
route is properly lined and no conflicting movement is occupying or authorized to enter the track between that signal and the next absolute signal governing movement.
when the train receives these instructions, “After stopping, (train) at (location)
has authority to pass signal displaying stop indication,” specifying the route where applicable, the train must move at restricted speed.
Conflicting movement. When the control operator has stopped a conflicting movement, he may then authorize another train to proceed in the same limits, advising both crews of the movement to be made. If the stopped movement is later permitted to proceed, that train must move at restricted speed until its leading wheels have passed the next governing signal or the end of the block system.
Stop And Restricted 8.12 At a signal displaying a stop and proceed indication, the train must stop, and then proceed at restricted speed until the leading wheels have passed the next governing signal or the end of the block system, unless given proper authority.
Authority to Enter Main Track 8.13 Within CTC territory and manual interlocking limits, the control operator or proper authority must authorize the train to enter the track at a hand-operated or spring switch where no governing signal exists. The control operator must verify that there are no conflicting movements before giving the authority. In ABS territory, when authorized to enter the signaled track, a crew member or switch tender must open the switch and wait five minutes at the switch to establish block signal protection. At the end of five minutes, if the employee does not hear or see movement approaching, the train may enter the signaled track. At a crossover, line the switch in the track the train is on, wait the five minutes, then line the other switch of the crossover.
