Here's the latest info: on Tuesday, July the 6th at around 9:00 am, there's going to be a 3 or 4-car train (S200) at Tuscany station for the official unveiling/commencement of service with representatives from all 3 levels of government, Transit and media expected to attend. The mayor will then drive the train to Dalhousie station.
