TTC's ATC signal upgrades now extend from Vaughan Metropolitan Centre Station to Rosedale Station

The TTC is pleased to announce that its upgraded Automatic Train Control (ATC) signalling system is now operational between Vaughan Metropolitan Centre and Rosedale stations.

Upgrades and testing were completed during this past weekend's subway closure with the system going live when full subway service resumed on Saturday. Portions of the TTC's signal system date back to the 1950s when the subway first opened. In addition to reducing signal-related delays, ATC increases safety of the subway, improves travel times and lowers operating costs.

"Despite the ongoing pandemic, the TTC has been hard at work upgrading the transit system to make it more efficient and effective. With ATC signals on a big stretch of our subway system, we can ensure that we are getting people moving across this city as quickly as possible. I want to thank the TTC and all of the operators and workers who have been working throughout the pandemic so we can not only provide continued service to riders but get important repair work done," said Mayor John Tory.

"The state-of-the-art ATC signalling system is already improving reliability and capacity on Line 1. I am very pleased to see ATC installed and in-service from Queen to Rosedale. Torontonians will continue to see better and better subway service as this project moves northward," said TTC Chair Jaye Robinson.

"Upgrading our signal system is essential to our ability to provide the best service possible for our customers," said TTC CEO Rick Leary. "ATC will improve existing service and customer flow and ensure we are ready to accommodate the planned growth our system will see in the decades to come."

TTC crews completed the stretch between Queen and Rosedale stations on Saturday. The previous phase of the ATC project, between St Patrick and Queen stations, was completed in February.

This milestone in ATC installation means fewer delays associated with the older fixed-block signalling system along the majority of Line 1, and improved service. It also means access to an additional turn-back location, at College Station, which provides more flexibility in the event of an operational issue on the line.

The new ATC area required 168 beacons, 12 trackside radios, 40 axle counters, 16 signals and included two weekend closures and one single day closure - just to fully test and commission into revenue service. Crews have been laying the actual ground work for the area since last year.

As installation of ATC continues, weekend closures will continue to be required. As always, the TTC will advise customers in advance of these closures and alternate service plans.
