Lower Bay
Lower Bay is an abandoned subway station on Toronto's Bloor-Danforth subway line, located at the intersection of Bay and Bloor Streets in the heart of downtown Toronto. Upper Bay station is still in use, known simply as Bay Station to its users, with Lower Bay shut off to the public since 1966.The station was in service for six months as part of an experiment where all Toronto subway lines were interlined. It was discontinued due to confusion and delays, although many argue that it was politically motivated and that the experiment was sabotaged by the TTC, designed to fail from the start.
It is now used to train new operators, allow trains to change lines, and for various filming projects. It has acquired a legendary status amongst so-called urban explorers, who often brave a host of dangers to gain access to the now-abandoned station.
