Picc-Vic tunnel
Picc-Vic was a proposed, and later cancelled, underground railway designed in the early 1970s with the purpose of connecting two major mainline railway termini in Manchester city centre, England. The name Picc-Vic was a contraction of the two key station names, Manchester Piccadilly and Manchester Victoria. The proposal envisaged the construction of an underground rail tunnel across Manchester city centre. The scheme was abandoned in 1977 during its proposal stages. The view was that the scheme still retained two large and expensive-to-maintain terminal stations in Manchester while other similarly sized cities had reduced their terminals to one. In 1992, the Metrolink system opened and linked both stations via tram, to an extent negating the requirement for a direct rail connection. In 2017, the Ordsall Chord became operational; an overground railway scheme directly linking Manchester Piccadilly and Manchester Victoria in a comparable fashion to Picc-Vic.
