CTC

An Automatic Block Signal system divides track into blocks protected by wayside signals that display aspects based on the occupancy of the block ahead, without dispatcher intervention.

CTC is a signal and train control system that allows a remote dispatcher to remotely operate switches and signals over a defined territory, managing all train movements from a central location.

A railroad dispatcher is the operations control employee responsible for authorizing and managing all train movements within an assigned territory, issuing track authorities, and coordinating with crews, MOW, and maintenance departments.
