CTC Rules

I spent some time checking on how the new CTC (Centralized Traffic Control) system being installed on the Red Deer sub between Calgary and Red Deer is progressing, contractors hard at work on this morning near mile 38.


CTC is commonly found on high- or medium-density lines, where the signal equipment cost can be justified by the reduction in train delays. Conceptually, CTC is a series of interlockings all controlled by one person. Trains are governed by signal indications, some of which provide movement authority. The traffic-control machine or computer software is designed so that conflicting authorities cannot be granted. From a console, now typically a computer screen, the dispatcher remotely controls signals and powered switches, which are most often found at the ends of sidings and at crossovers between main tracks. Trains need only to observe the controlled signals to obtain movement authority

I was hoping to catch a train approaching from the south to place in this photo with the Viterra grain terminal seen in the distance, however with no luck on this morning, I'll return.
