Today I was walking through Dundas west station and saw this announcement board. Its based on GPS in the street cars, months back I had taken a picture of the trail signs at Spadina (Project 365-068: TTC Streetcar Tracking). That struck me is about this sign today is that Dundas West used to have sides forecasting the next arrival of street cars. Over a decade ago they had screen that showed the next schedule vehicles, sure it was based on where they should be and not where they are. But like the Time Line Schedule I always found it helpful.
