The TTC is again resignalling the University section of the 1 Yonge - University - Spadina subway this Sunday, March 10. The resignalling modernizes the TTC’s signals, relays, wiring and cabling equipment, much of which was originally installed when the University line opened 50 years ago on February 28, 1963.

Renewing the signalling system in the subway is a major state-of-good-repair project. The TTC is upgrading its infrastructure across the system to make sure it can continue to deliver safe, reliable service to passengers.

The TTC has already performed weekend resignalling:

It has scheduled more work:

  • Sunday, March 17 (starting at 12:01 a.m.); and
  • all day Saturday, March 23 and Sunday, March 24.

Regular subway service resumes each Monday at 6 a.m.

This Sunday, subway trains start and end their trips at St. George and Union Stations. Trains operate between Finch and Union Stations and between Downsview and St. George Stations only. Frequent, accessible buses replace the subway service.

Due to construction on Front Street West resulting from the TTC’s project to build a second subway platform at Union, the shuttle buses will not drop off or pick up passengers at Union Station. Instead, they operate between St. George and St. Andrew Stations on the University branch of the line and also serve King Station on the Yonge branch.

The buses drop off and pick up passengers at stops along the route:

  • from 9 a.m. until 10 p.m.: every 2 to 3 minutes; and
  • from 10 p.m. until 2 a.m. Monday: every 3 to 5 minutes.

While the subway is closed, southbound buses start their trips in St. George Station bus terminal, south-side platform (where buses operating along the 26 Dupont route usually stop), then proceed:

southward along Bedford Road;
eastward along Bloor Street West;
southward along Queen’s Park, Queen’s Park Crescent West and University Avenue;
eastward along King Streets West and East (stopping to drop off passengers at St. Andrew and King Stations);
northward along Church Street;
westward along Richmond Street East; and then
southward along Victoria Street to Adelaide Street East,
ending their trips.

Northbound buses start their trips on Victoria Street at Adelaide Street East, then proceed:

eastward along Adelaide East;
southward along Church Street;
westward along King Streets East and West (stopping to pick up passengers at King and St. Andrew Stations);
northward along University Avenue, Queen’s Park Crescent East and Queen’s Park;
westward along Bloor Street West;
northward along St. George Street (stopping to drop off passengers at the St. George entrance to St. George Station);
eastward along Prince Arthur Avenue; and then
southward into St. George Station bus terminal,
ending their trips.

To accommodate passengers traveling between the University and Yonge branches of the subway, the TTC is increasing the frequency of service along the 505 Dundas route by adding four more streetcars between 8 p.m. and 1:45 a.m. The extra, short-turning streetcars significantly increase the number of cars operating between St. Patrick and Dundas Stations.

Eastbound extra streetcars start their trips on McCaul Street north of Dundas Street West, operate along the regular route to Dundas Street East and Church Street, then proceed:

southward along Church;
westward along Queen Street East; and then
northward along Victoria Street to Dundas East,
ending their trips.

Westbound extra streetcars start their trips on Victoria Street south of Dundas Street East, operate along the regular route to Dundas Street West and Spadina Avenue, then proceed:

northward along Spadina Avenue;
eastward along College Street; and then
southward along McCaul Street to Dundas West,
ending their trips.

Since the TTC is also overhauling elevators at St. George Station, it will station Wheel-Trans accessible buses at Bathurst, Eglinton West, Bloor - Yonge and Union subway stations to accommodate seniors and persons with disabilities who use wheelchairs, scooters and other mobility aids:

  • Passengers traveling on the 2 Bloor - Danforth line from west of Bathurst Street should exit the subway at Bathurst Station to board the Wheel-Trans vehicle.
  • Passengers traveling on the 1 Yonge - University - Spadina line from north of St. George Station should travel to Eglinton West Station to board a Wheel-Trans vehicle
  • Passengers who would usually exit the subway at St. Andrew or Queen’s Park stations should travel south to Union Station to board a Wheel-Trans vehicle.

Renewing the signalling system

TTC contractors installed the current block-signalling system in the 1 Yonge - University - Spadina subway between Union and St George stations 50 years ago. The system has reached the end of its useful life; the process of installing a new signal system is now under way.

The resignalling project modernizes TTC subway signals, relays, wiring and cabling equipment and lays the groundwork for the upcoming automated train control system or ATC. ATC allows trains to speed up and slow down more smoothly, improving safety and passenger comfort. It also provides consistent station-stopping performance, prevents platform overshooting and allows the TTC to introduce platform-edge doors in the future.

Over the past three years, the TTC has installed about 91 kilometres (300,000 feet) of cable and 400 pieces of equipment as part of this project. Crews have made 100 new cut-outs in the concrete structure to accommodate the new ATC equipment.

The TTC has also installed three new double crossovers at College, St. Clair and King Stations to increase service even more once ATC is operating. The new crossovers let subway trains end their trips at these stations during an emergency, switching over from one track to another and then heading in the opposite direction along the line.

The TTC expects this new signal system to be fully functioning on the line by 2018.
