The Liverpool Road railway station complex is significant as it was here that the passenger terminus was invented, and concepts such as separate facilities for the rich and the poor first appear here. The station is the oldest mainline station in the world. The booking hall for first and second class passengers was on Liverpool Road, and there were separate stairs up to the separate first floor waiting rooms and the platform. There was a sundial over the first class entrance, since up to 1847, Manchester Corporation used 'local time' and that was set by the sun. In 1847, the Corporation adopted 'railway time'. Adjoining the station are the 1830 warehouse (300 ft X 70 ft) with 6 spur tracks, and the three-storey long, No. 1 Cotton Store built in 1831, and the similar No. 2 Cotton Store. However this was period of rapid expansion. The 1830 warehouse had been built within 4 months by David Bellhouse Jnr. In 1837, the station buildings were extended by the Grand Junction Railway and a new goods shed built. Warehouses now covered , and had a floor area of . The passenger station closed on 4 May 1844 when the line was extended to join the Manchester and Leeds Railway at a new station situated in Hunt's Bank and it all became a freight terminal. The cotton stores and the goods sheds were demolished in the 1860s when the London and North Western Railway expanded the goods station. In 1844 there were six railway lines connecting the world to Manchester, and Léon Faucher commented that there were 15 or 16 seats of industry that formed this great constellation. Two more railway warehouses can be seen, the 1869 London and North Western Railway Bonded Warehouse on Grape Street with its separate viaduct over Water Street and the four-storey 1880 Great Western Railway Lower Byrom Street Warehouse. The Lower Byrom Street Warehouse is now part of the Museum of Science and Industry, while the Grape Street warehouse is used by Granada Studios as studios, rehearsal space and offices. Regeneration Castlefield regeneration dates from 1972, when the Greater Manchester Council carried out archaeological investigations in the area. The Liverpool Road goods depot closed 8 September 1975, and the GMC made a survey of the site and it became the North Western Museum of Science and Industry in 1978.
