When a call light is on, who is notified and by whom?
Train dispatcher is notified and any employee who sees it, unless on a moving train.
Manual Interlocking and CTC territory. What is the phraselogy to authorize a train past a signal displaying Stop indication? Also what speed are they governed by?
"After stopping, (train) at (location) has authority to pass signal displaying stop indication." also, specify the route when applicable. Train must move at restrictive speed.
Both Manual interlocking and CTC. If a train is at a signal displaying a stop indication who must they contact immediately?
Control operator
Under CTC territory. What is the exception to the stop indication rule?
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 movement to be made.
Under Manual interlockings: What is the exception to the stop indication rule?
When the control operator has stopped a conflicting movement, he may then authorize another train to proceed, advising both trains of movements to be made.
Entering signaled track at hand-operated or spring switches. Within CTC territory and manual interlocking limits, you must have what to get on main track?
Control operator MUST authorize the train to enter the track where no governing signal exists. Verify there are no conflicting movements.
Entering signaled track at hand-operated or spring switches. Within ABS territory you must do what to get on main track?
Crew member must open switch and wait 5 minutes at the switch to establish block protection.
What are the steps for hand-operation of a dual controlled switch?
-unlock the switch lock - place selector lever in HAND position- operate the hand throw lever, - line the switch for intended route, - return the switch to power
9.13 what must be done if he dual control switch can not be operated or does not indicate that the switch is lined and locked?
Dispatcher must authorize movement past the stop indication and instruct the employee to operate the switch by hand.
9.13 When a dual controlled switch has been put into hand positon, when is the power re-applied to the switch?
After at least one unit or car has passed over the switch points. Unless otherwise instructed by the dispatcher.
Initiating movement between signals. Move at restricted speed until the leading wheels have passed the next governing signals when?
The train enters a block with no governing signal, the previous signal indication is unknown, movements in the opposite direction from which the block was entered.
