Locomotives were constructed and maintained at works inherited from constituent companies at Eastleigh, Ashford and Brighton. The largest was Eastleigh, which was built by the LSWR in 1909 to replace the cramped Nine Elms Locomotive Works in South London. Brighton had been constructing locomotives since 1852 for the LBSCR, and built 104 of 110 Bulleid Light Pacifics between 1945 and 1951. Ashford was inherited from the SECR, and had been built in 1847, and was the works that constructed half of the SR Q1 class. Ashford completed its final locomotive in March 1944, a War Department Stanier 8F 2-8-0 number 8764.
