[[Canadian National Railway]]'s '''Kingston Subdivision''', or '''Kingston Sub''' for short, is a major [[railway line]] connecting [[Toronto]] with [[Montreal]] that carries the majority of CN traffic between these points. The line was originally the main trunk for the [[Grand Trunk Railway]] between these cities, although there has been some realignment of the route between these cities. The majority of the Kingston Sub runs close to the northern bank of [[Lake Ontario]] and the [[Saint Lawrence River]].

'''The Kingston Subdivision''' ('''Kingston Sub''' for short) is a major [[railway line]] owned and operated by the [[Canadian National Railway]] (CN) in the Canadian provinces of [[Quebec]] and [[Ontario]]. It runs for approximately 322 miles (518 km) from [[Dorval]] (a suburb of [[Montreal]]) west to [[Toronto]] and carries the vast majority of CN traffic between the two cities. The line runs along the northern shore of [[Lake Ontario]] and the [[St. Lawrence River|Saint Lawrence River]], largely over the rail alignment originally built for the [[Grand Trunk Railway]] in the 1850s.

The infrastructure consists of twin tracks, on which over 50 pieces of interlocking [[Crossover (rail transport)|crossover]] tracks are grafted all along the subdivision. The extra length of these crossover tracks allows for high speed track interchange. Trains are allowed to change tracks at up to 45 miles per hour. The governing traffic control system is [[Centralized traffic control|CTC]]. Since 1995, no [[Track Warrant Control|OCS]] operation clearance forms need to be filled by train conductors on the Kingston Subdivision. CTC signals thus provide both permission and authorization for train movements, as is the situation with most main line operation at CN.

The entire subdivision is double-tracked and contains over 50 interlocking [[Crossover (rail transport)|crossovers]]; these crossovers are built longer in order to allow for high speed track interchange - many permit trains to change tracks at up to 45 miles per hour. The entire subdivision is governed by [[Centralized traffic control]] (CTC). Since 1995, no [[Track Warrant Control|OCS]] operation clearance forms need to be filled by train conductors on the Kingston Subdivision. CTC signals thus provide both permission and authorization for train movements, as is the situation with most main line operation at CN.

Just east of [[Newcastle, Ontario|Newcastle]], east of Toronto, the line is joined by the [[CP Belleville Subdivision]], [[Canadian Pacific Railway]]'s similar mainline route. The two remain nearly side-by-side to the east of [[Belleville, Ontario|Belleville]], where the Belleville sub turns north to [[Smiths Falls, Ontario|Smiths Falls]]. Sections of the Kingston Sub are no longer owned by CN. In particular, CN mainline freight traffic in the Toronto area no longer follows the Kingston Sub, and is re-directed north of the city along the [[CN York Subdivision|York Sub]]. The section between Pickering Junction and [[Union Station (Toronto)|Union Station]] in downtown Toronto has been sold to [[Metrolinx]] for [[GO Transit]] service, part of their [[Lakeshore East line]].{{cite web |url=http://www.cn.ca/en/news/2011/03/media_news_metrolinx_cn_kingston_20110330 |title=Metrolinx acquires key commuter-rail segment of CN's Kingston Subdivision east of Toronto Union Station |author= |date=30 March 2011 |work=News Articles |publisher=CN |quote=The rail line acquired by Metrolinx from CN is composed of the two- and three-track rail corridor east of Union Station in downtown Toronto to a junction near Whites Road in Pickering, Ont. |accessdate=3 March 2016 |archive-url=https://web.archive.org/web/20160307123740/http://www.cn.ca/en/news/2011/03/media_news_metrolinx_cn_kingston_20110330 |archive-date=2016-03-07 |url-status=dead }}
