The canal wharf was capstan-shunted. The positions of the turntables used to access the lifts, the capstans and bollards as at 1955 are all shown on the 1:1250 map on old-maps.co.uk.

The Birmingham Level of the canal into the yard was at 450' above sea level. access to the main yard from Pitsford Street was at about 420'. The turntables in the main yard gave access to the two tunnels under All Saints Street to the lift. The link in Post #2 above has a lot of pictures of the area.
On Google Street View at the junction of All Saints Street, Pitsford Street and Crabtree Street you can still see the Farriers & Wheelwrights shop, Vet's office and part of the stables block.
