1. The crew must be taken out of service.
2. The Dispatcher must be taken out of service.
3. The movement must come to a stop and the Dispatcher notified.
4. None of the above.
5. All of the above.
In application of Special Instruction 133-2, the movement of the train need not stop and the Dispatcher notified if:

1. The Dispatcher will be taken out of service.
2. The train crew will be taken out of service.
4. The train may continue at Restricted Speed.
4. The train may continue at normal speed.
Basically a "Block" is put on the dispatcher's computer to prevent the dispatcher from accidentally reversing the switch or lining a train into the out of service track.......for example if the dispatcher leaves his/her desk for a bathroom break and the adjoining dispatcher steps in they can't line a train into the oos track by accident if they don't know work is being done there.
