This was Manchester Central. Today it is better known as GMEX, the venue of the Labour Conference this week.
Subterranea Britannica (from which I have borrowed the photograph) has the history of the station:
From Manchester Central trains ran on the CLC network to Liverpool, Chester and Stockport. The Midland railway ran express trains to London St. Pancras.
These trains continued until 1968 when they were diverted to Manchester Piccadilly but after a few years discontinued. One of the most famous trains to run in the second part of the 20th Century was the Midland Blue Pullman introduced in 1960 which ran from the station until 1966 by which time the West Coast Main line had been electrified.
