An Ottawa city councillor says it's time for OC Transpo to end its E1 express bus, arguing that the route has become redundant and that its resources could be better spent improving transit elsewhere. OC Transpo E1 Express route between downtown and Blair Station. The E1 is a weekday peak-period express bus connecting Blair Station with downtown, offering commuters an alternative to Line 1. OC Transpo did not say by how much ridership had declined. His preferred solution is a non-stop shuttle between Fallowfield Station and Tunney's Pasture, which he says would give commuters faster trips without duplicating existing rail service.
