The Yonge-University-Spadina line could be described in simple terms as a 'V' shape with Union Station located at the bottom of the 'V'. The western leg extends north to Downsview Station and the eastern leg extends north to Finch Station. The Bloor-Danforth Line runs predominately west to east between Kippling Station in the West and Kennedy Station in the East. This line crosses both of the north-south legs of the Yonge-University-Spadina line and has connections to it at Spadina, St. George and Bloor-Yonge stations. The Sheppard Line runs east from Sheppard/Yonge Station on the Yonge-University-Spadina line to Don Mills Station. The Scarborough RT is an above grade and elevated rapid transit line that runs east from Kennedy Station at the eastern end of the Bloor-Danforth Line to Scarborough Town Centre and also McCowan.
There are currently 29 Toronto Subway stations including all 5 stations on the Sheppard Line that are wheelchair and scooter accessible. These stations all have elevators to provide access to the stations. About 50% of the trains (identified with the blue wheelchair symbol) provide special positions to accommodate wheelchairs, however all trains can be boarded by wheelchairs.
Toronto Subway Trains run every 2-3 minutes during rush hour and every 5-6 minutes the rest of the time on the Yonge-University-Spadina Line and on the Bloor-Danforth Line.
