daily between 4:55am and 11:00pm every 15 minutes, making approximately 68 trips per day. Route From Union Station, the UP Express heads northwest along the existing GO Transit Kitchener line. This section of track between Bathurst Street and Highway 427 was upgraded as part of GO's Georgetown South Project, which improved infrastructure along the route to accommodate the UP Express, GO Transit, Canadian National, and Via Rail services. The UP Express makes two intermediate stops at Bloor and Weston GO stations. Bloor Station was redesigned for better access and connection to GO Transit, and Metrolinx is working towards a future direct connection to the Dundas West subway station. Beyond Highway 427, a newly constructed rail spur carries the UP Express from the Kitchener line to the airport, forming the longest elevated rail line in Ontario. The elevated spur to Pearson Airport reaches a maximum height of , offering a view of the Downtown Toronto and Mississauga City Centre skylines. At Pearson, the UP Express arrives at Terminal 1, where riders can connect to the existing Link Train inter-terminal shuttle to Terminal 3 and the Viscount parking garage. Stations At Toronto Union Station, UP Express departs from a newly constructed station immediately west of the railway station of the same name, connected to it by the SkyWalk. The UP station features numerous amenities including a fully enclosed platform and waiting area, a guest services desk, a café, a gift shop and a licensed lounge. Whereas other GO Transit lines use low-floor vehicles accessed from low-level platforms, the Union Pearson Express is operated with high-floor vehicles necessitating high-level platforms. As a result, at Bloor and Weston stations, UP operates from its own dedicated platforms adjacent to the Kitchener line platforms. UP Express trains will stop at Mount Dennis Station in the future, in order to connect with the under-construction Line 5 Eglinton, which is scheduled to open in 2023. Rolling stock The Union Pearson Express uses Nippon Sharyo DMU trains. The fleet consists of 18 diesel multiple unit (DMU) cars, as four three-car and three two-car sets. Initially, on 1 March 2011, Metrolinx announced that it had chosen to buy 12 DMU cars (six two-car trains) from Nippon Sharyo at a cost of $53million, for the service. This was later expanded to 18 DMU cars (adding one car to each train via an option order). This brought the cost to million. The
