Signal Modernization

The Union Station Rail Corridor renewal program will allow us to get ready for a doubling of train traffic over the next 20 to 30 years.

This will be achieved through signal system renewal, computer-based train dispatching, consolidating dispatch offices, providing new routings to the Union Station platforms, eliminating track bottlenecks, increasing train speeds, improving platform access, and adding new snow clearing devices.

Signals are the stoplights and traffic police of the train network. A modernized system will improve reliability and allow trains to move faster, while maintaining GO's high safety standards.

The vintage signalling system around Union Station continues to operate safely, but has become increasingly expensive to maintain. The limitations of the system are being felt more and more as train volumes increase; this is particularly true when there are delays or bad weather.

The new signal system will allow for faster recovery from train delays or equipment malfunctions and will be designed for increased train speeds. It will also streamline and consolidate operations into one control centre. When combined with GO Transit's security and bus operations control centres, the signal centre will provide better, most cost-effective service.

This project also includes work on the cable network, retaining walls, maintenance access roads that run parallel to the tracks, and the gas lines that supply heat for snow blowers on switches.

Overall Target Completion Date: 2014

STATUS

• Design began in January 2008 and construction started in late 2008.
• Installation of switch clearing devices (used to control the build-up of ice and snow) is being done in parallel with upgrading tack switches.
• 78 devices installed in 2008-2009, 82 more to be installed in the next two years.
• As switches are replaced, new switch clearing devices will be installed.
