One of the major problems with not only Guide Bridge and the route to Piccadilly, is the basic shortsightedness of the de-quadrafying of the route. I remember in the early 1970's that there were FOUR lines from Ashbury's through Guide Bridge as far as Hyde North. It seemed to me that these lines always seemed to be busy. Although I will accept that the Woodhead route has since been closed BUT all the freight over Woodhead didn't go through Guide Bridge, but left the route at Godley Junction to head off through Stockport Tiviot Dale and on to Widnes.
If the four lines were reinstated, along with the closed platforms at Guide Bridge, then the route would have more capacity. All these problems are caused by the desire of then BR, not only to close as many lines as they felt they could get away with, BUT to remove all what they thought was 'redundant' track and facilities. Many of which we are now having to replace at much greater cost than if we had kept them in the first place. I very doubt that the supposed savings that were to come for all this reduction ever amounted to much at all.
Just another example of cost cutting, that actually costs more than we ever saved.
