The SER Q class was a class of 0-4-4T steam locomotives of the South Eastern Railway . The class was designed by James Stirling and introduced in 1881. These locomotives should not be confused with the later SR Q class 0-6-0 .
Rebuilding [ edit ]
The locomotives passed to the South Eastern and Chatham Railway in 1899 and 55 were rebuilt by Harry Wainwright to class Q1 between 1903 and 1919.
Numbering [ edit ]
Thirty-two unrebuilt locomotives survived into Southern Railway ownership on 1 January 1923 with random numbers between 6 and 424. All had been withdrawn by 1929.
