The total length of the track is 20.8km, which is open for passengers and does not count maintenance track or secondary tracks. On the Confederation Line there is 12.8km of track and on the Trillium Line there is 8km.
The Confederation Line operates Monday to Thursday 5am-1am, Friday 5am-2am, Saturday 6am-2am and Sunday 8am-11pm. The Trillium Line operates weekdays 6am-12am, Saturday from 6:30am-12am and Sunday from 7:30am-11:30pm.
When the Trillium Line is not operating, a replacement bus service is provided. Route 107 activates and runs with limited stops between Bayview Station to Greenboro Station. As of September 2nd, this route will be renumbered R2.
The Confederation Line uses a Communication Based Train Control (CBTC) system with in-cab signaling. Movement allowance and speed limits are displayed in a monitor inside the cab of the train rather than with track-side signals. The track side signals on the Confederation Line are located at switches and indicate the position of the points on the switch.
The Trillium Line uses a more traditional signaling system called Centralized traffic Control (CTC) that uses the same type of track-side signals that are found on other mainline railways in Canada. Since the Trillium Line intersects with a VIA rail line and their signaling systems are connected, the Trillium Line is dispatched by VIA from Montreal. The Trillium Line is also equipped with a train protection system called “Indusi”.
The Indusi system is a train protection system used on the Trillium Line. The system uses track side magnets and a transmitter equipped on the train to enforce signals and speed limits. The track side magnets are indicated with black and white signs showing a profile of a rail and the word “Indusi”. As an example, if a train were to pass a red signal, the track side magnet located next to the signal would trigger an emergency stop of the train.
