LSWR Drummond steam railmotor Profile and Models

To provide an economic service on the L&SWR and London, Brighton & South Coast Railway (LB&SCR) joint branch from Fratton to Southsea two steam railmotors were built by the L&SWR in 1902, entering service in April 1903, and designated as K11 Class. The first unit was lent to the Great Western Railway, returning with favourable reports.[ However, when introduced in summer 1903 the units struggled with passengers on the gradients on the line and it was discovered that the GWR had trialed the unit on level track and without passengers. The units were rebuilt with a bigger firebox and boiler. A further two batches were built with slightly different designs, designated as the H12 and H13 classes from 1904 to 1906.  After the outbreak of World War I limited the work available for railmotors the joint stock was taken out of service in 1914 and by 1916 only three units remained in service, to be withdrawn in 1919.
