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.


The atrium, which still needs provincial funding approval, is part of an $85-million renovation project.
