Images found online have shown inside the Scotland Street Tunnel, which has lain empty since the early ‘80s.
Work began on the structure in the early 1840s, which would forge a link between Canal Street Station (now known as Waverley) and the north of Edinburgh. It would run underneath Scotland Street, Dublin Street and St Andrew Square.
Urban explorer James Perry filmed his trip into the tunnel, which is never advised, and uploaded the experience to YouTube. In the footage, we see the now derelict passageway which once saw thousands of passengers a day travel from one end of the city to the other.
