Spalding has two platforms. Platform 1, adjacent to the station building, is mainly used for southbound services towards Peterborough and terminating trains from Peterborough, but is also used by some northbound through services towards Sleaford and Lincoln; Platform 2 can only be used by northbound services. The station used to have seven platforms: five through faces (up main and two islands) and two terminal bays, with services to March and Sleaford on the Great Northern and Great Eastern Joint Railway, Bourne and on the Midland & Great Northern Joint Railway and the Great Northern "Lincolnshire Loop" line to and then onwards to and Grimsby. There was also, past the Northern Junction a freight line going off to the former British Sugar plant. Only the routes to Werrington Junction, Peterborough and are still in use and the station has been remodelled and downsized considerably since the demise of the March line in 1982.
