APPENDIX C Chicago Transit Authority 5511—76 General Operations Division Supercedes 5215-76 Transportation Department SERVICE BULLETIN TO: Motormen, switchmen and Yard Foremen SUBJECT: Train operating procedures on all rail routes at permissive

signals displaying red aspect

EFFECTIVE: Wednesday, December 8, 1976

ON ANY MAIN LINE TRACK, BETWEEN TERMINALS:

When a train receives a red aspect at an interlocking approach signal or an automatic block signal, or receives a red or flashing red aspect of a cab signal, it must be brought to a stop and must NOT proceed until the employee operating the train has been instructed to do so by the controller.

If the reason for the stop is a train ahead which can be expected to proceed shortly, wait for the signal aspect to change to a "proceed" indication. If the reason for the stop is not evident, or if it does not clear within a reasonable time, call controller for instructions.

The train MUST REMAIN STANDING until the controller has issued specific instructions, for example, to authorize the train to proceed after operation of the track trip manual release (key—by) or, in cab signal territory, to proceed on the "flashing red."

If communication cannot be established with the control center, the train will proceed to the next wayside signal bond or wayside signal at not to exceed 15 MPH (on sight*). If the signal then fails to clear, the train will proceed from block to black at not to exceed 15 MPH (on sight*) to the first point where communication can be established with the control center by trainphone or telephone.

WITHIN YARD LIMITS, and AFTER ARRIVAL IN A TERMINAL:

When cab signal displays flashing red aspect, it is permissible to proceed on sight without calling controller only under the following conditions:

a. An arriving train may be operated into the yard or turnback after it has made the regular station stop at the terminal and the passengers have alighted.
