West Toronto Diamond

Mile 4.7 CPR Galt Subdivision
Mile 5.8 CPR North Toronto Subdivision
Mile 4.8 CNR Weston Subdivision
(Former Brampton Sub.)

After 130 years the West Toronto diamond is no more. Friday, May 23, 2014 with the passage of the last westbound GO train Number 269 to Georgetown (due Bloor Street 1900) the GO (former CN) Weston Subdivision main track was closed. Beginning Monday morning the first GO train from Mount Pleasant went underneath the CPR North Toronto Subdivision.

Heading north over the diamond cab car 221 trails GO 269 engine 615 on GO (former CN) Weston Subdivision westbound on double yellow signal to Georgetown is the last train to cross the diamond with CPR North Toronto Subdivision. New track underneath being tamped in preparation for cutover. 1900 Friday, May 23, 2014 Paul Cordingley

Note: Other last movements were eastbound (southward) from Sarnia VIA 84 engine 6459.due 10.40 A.M. Westbound CP T15 engine 2254. Eastbound CP 142 engine 8933. Recorded by Paul Cordingley.

Massive undertaking by Metrolinx is to accommodate the new Union-Pearson Express, all day long passenger trains between Union Station and Pearson International Airport due to begin in May 2015. It will also facilitate additional GO commuter trains on the Kitchener (formerly, Georgetown) line. VIA Rail passenger trains also use this line via Stratford to London.

Note: Following changes to signals an Operating Bulletin was issued as follows: Effective after 1900 Thursday June 12 2014, the remotely-controlled interlocked junction and railway crossing at grade at West Toronto is permanently removed from service.

This interlocking was originally installed circa 1909 to protect the multiple routes over diamonds on the many lines that first crossed in May of 1884 and added to as more railways met. In other words 130 years of history has come to an end.

West Toronto diamond looking southeast. Men are working on the MacTier Subdivision diamond with the double track CNR Weston Sub. originally GTR broad gauge (5' 6") to Stratford. Galt Sub. originally CVR main line to St. Thomas at far right. Note the crossovers and station platforms. Crossways double track is North Toronto Sub.originally O&Q main line from Havelock The arrival of the O&Q in early May of 1884 created the need for the diamond. Far left single track is Old Bruce Service track, originally TG&B narrow gauge (3' 6") main line through Weston to Bolton and Orangeville. April, 1923.

Double tracking of the North Toronto Sub. in 1905 was likely the impetus for interlocking installation c. 1909

Weston Road Viaduct
Construction details.

Note: This bridge was closed to traffic in July 1972 due to deteriorated condition and the lack of government funding to rebuild it caused it to be demolished in July of 1981 although the approaches remained for some time before being removed. Traffic congestion has existed ever since as only a narrow ancient Keele Street underpass remains in the area.

G3 2318 could be a time table train (no signals displayed) from Mac Tier backing into the yard on westbound track off the
North Toronto Sub. Note low coal supply and direction of smoke and steam. Engineer not visible meaning movement being controlled by tail-end crew on the van. Typical method of yarding a train although at other times a southbound train would head down the Galt Sub. past West Toronto Depot and back in from there.

Note: The van and tailend crew have been left at Parkdale. The reason for this practice is uncertain although it may be related to the eastbound train 910 "Mae West" which handled LCL from King Street shed to Montreal.

P2 class 5370 a London engine is backing over the diamond eastward from Lambton with its van to lift its train in
Leaside yard. It will later return westbound for London right past this same point.
This was a common practice in the mid-late 1950's when this photo was likely taken. Bud Laws Collection

Note the large steam delivery pipe along the running board. This was used in work train service such as powering a Lidgerwood steam winch unloading ballast or for thawing culverts in winter. It is more visible on 5361 here:

Originally an all-mechanical interlocking built 1908 by Saxby and Farmer in England controlled the diamond through a system of rods and bell cranks. Installation, operation and maintenace; 100% CPR. It consisted of 44 levers controlling 21 switches, derails and locks plus 17 signals (6 levers were spare). This system was finally replaced in March 1965 with modern CTC controlled by a train dispatcher at Union Station. The tower was demolished in September 1964 temporarily replaced by a small shanty and around-the-clock switchtenders to manually control tracks during the changeover.

Note the crank telephone. One long was the ring on the party line which ran throughout the yard.

Interlocking controls mean conflicting movements are not possible providing complete safety.

On two separate days a year apart Fred Clark spent a long day photographing and taking notes
of operations across West Toronto diamond. Here are the results. Note time explanation above.

Both of these local jobs appeared again. Later in the day 6603 returned from Lambton Yard moving eastward across the North Toronto Sub. At 1545 the 7024 reappeared making two more movements, first eastward shoving with van ahead
and then at 1550 westward with engine cab leading up the MacTier Sub. obviously one of the Emery Road Switcher jobs.
