CN Bala Subdivision
The CN Bala Subdivision is a major railway service line in Ontario running between Toronto and Capreol in Northern Ontario, thus forming part of CN's transcontinental link between Southern Ontario and Western Canada. The majority of the line serves transcontinental freight traffic along with VIA's transcontinental line The Canadian. Also within the Greater Toronto Area, service is also shared by the Richmond Hill line of GO Transit from Downtown Toronto to Richmond Hill just before the border of Aurora. The section between the Union Station Rail Corridor in Downtown Toronto and the Doncaster Junction with the York Subdivision in the Thornhill area of Markham is owned by Metrolinx, whilst the remainder of this line is owned and primarily operated by CN. Therefore, freight train traffic serving the GTA does not continue into the downtown core but is instead rerouted at Doncaster Junction west along the York Subdivision to its main terminal, MacMillan Yard. Also, between south of Parry Sound and south of Sudbury both CN and its rival CP have implemented the use of directional running in order to relieve congestion on both of their respective parallel lines. Therefore, all Southbound CN & CP traffic utilizes the CN Bala Sub whilst all Northbound traffic utilizes the CP Parry Sound Sub.External Links
