Glass roof to brighten Union depot
Historic train shed to be integrated into design as part of $85M revamp

The train shed at Union Station is a jewel on Canada's heritage map, but there's nothing that glitters about the dark, leaky roof that lends a dingy atmosphere to the platforms.
Now GO Transit has approved a plan to build a glass atrium that will brighten the area where passengers board and step off their trains.
The raised glass box supported by steel legs will also be lit from within to provide an attractive night view from above. Including an overhang to protect passengers from the weather, the centre atrium will cover about one-seventh of the 2.8-hectare train shed.
"When it was built, (the roof) was virtually invisible," said David Hopper, deputy program manager of HDI Joint Venture, the consultants working on the station redevelopment with GO.
Toronto has grown up around the station since it was completed in 1927, and the deteriorating roof is now overlooked by thousands of people living and working in downtown skyscrapers.
The atrium, which still needs provincial funding approval, is part of an $85 million renovation to the historically significant train shed at the south side of the station, owned by GO, which leases space to VIA Rail. Work on the shed, including restoration of the historic roof sections that will remain, is scheduled to begin late next summer and will take about 5 1/2 years to complete.
The glass atrium "really takes (Union Station) to the next level," said Hopper. "There's real city building potential here."
The train shed is a significant element of a $600 million modernization and renovation project that will help double Union's capacity to more than 80 million passengers per year by 2014.
Besides the new bus terminal and ongoing track and switch modernizations, GO is adding 15 new sets of stairs to platform areas and four covered teamways, which allow passengers to enter and exit the platforms from Bay and York Sts.
An improved concourse for waiting passengers is also to be built at the west end of the station.
The original open-air Bush train shed is one of only two in that design remaining in Canada. The other is in Winnipeg.
The first lightweight Bush shed was built in Hoboken, N.J., in 1907. It represented a departure from the glass balloon-type stations popular in Europe and was a forerunner to the canopy styles used in Vancouver and Los Angeles.
Considered to be of cultural significance by Parks Canada, the east and west ends of the shed's roof will be preserved for the unique latticework of angled steel on the shallow arch trusses. A green-roof element, planted with low-growing ground cover, is also part of the design.
In addition to the roof atrium, designers have tried to keep the platforms and track area light by using glass walls around the new stairways to the street and station.
The city owns the limestone building facing Front St. The third rendition of Toronto's main train terminus, it is built in the grand, symmetrical Beaux-Arts style.
Two of Union Station's outstanding architectural features have already been restored by the city: a skylight in the courtyard of the old CN offices at the west end of the terminal, and the west window in the main hall.
The station's main entry plaza on Front St. is being refurbished this summer.
