West Toronto Diamond
Coordinates: 43°40′02″N 79°27′36″W / 43.66722°N 79.46000°W The West Toronto Diamond is a Canadian railway junction in Toronto, Ontario. It connects the Metrolinx Weston Subdivision, which carries the GO Transit Kitchener line, UP Express and Via Rail Corridor passenger services, to the CP North Toronto Subdivision, which is the Canadian Pacific Railway's main freight line across Toronto. It is located near the intersection of Keele Street and Dundas Street in Toronto.
The West Toronto Diamond is often referred to as "the junction" and gives Toronto's The Junction neighbourhood its name.
The junction was originally controlled by a complex interlocking built by Saxby and Farmer which controlled 21 switches, derails and locks, plus 17 signals. The interlocking was controlled from an interlocking tower located at the centre of the junction. In 1965 the interlocking was converted from local control to remote control, operated by the CP Toronto Terminal RTC in Montreal.
