Manchester tracks north of Victoria Station c1985 (bw)
It's interesting to read this thread, Manchesters underground has long fascinated me.
As many of you have noted there is a cobbled entrance underneath Victoria Station behind Chethams music school. However there is another one which I believe links up to this road. It's found underneath the railway line on the north side of the station on the road red bank, although gated up, you can see down it for quite some distance.
I remember a surveying team went under the station on an inflatable boat along the river Irk in the nighties, does anybody have the report on this?
There is also an underground tram that I think is now disused, that runs to the main post office on Newton Street
The phone lines under Piccadilly are the remains of a cold war bunker that run from Ardwick to Piccadilly and on a short distance to near the river Irwell.
And finally one I have seen first hand is the remains of the underground Salford Junction canal that runs under GMEX and Granada Studios, it's just a selection of huge chambers that are now dry, this was used as an air-raid shelter during the Second World War, a wardens office still exists down there, an entrace chamber can be located to the right of the main entrance to GMEX.
