Condor contracted directly with TTC to provide a TMM based control office, 21 power switch machines, axle counter enabled track circuits and 4 control cases to enable automated routing of streetcars entering the newly rebuilt end of Russell Yard.

Condor was responsible for the design, manufacture, wiring, installation, testing and commissioning of the complete signal system – both the wayside and the control office. Microlok processors were wired in a hot standby configuration and were used for the software application signaling logic.

Train movements in the yard are controlled by a yard dispatcher using an entrance/exit based PC system TMM (Train Movement Manager).
