to operating on the line. No. 50 Whitechapel was purchased by the Municipal Borough of Sutton and Cheam in 1963 (after the originally intended purchase, No. 61 Sutton, had been cut up). The intention was to display the engine outside the new Civic Centre, and the engine was offered a home on the K&ESR until the work was completed. The engine was restored and used to haul the opening train on the preserved K&ESR in 1974. After slipping down the overhaul queue at Rolvenden, the engine was moved to the Spa Valley Railway by the owners (the engine still being owned by Sutton Borough Council) and restoration work commenced. No. 46 Newington has perhaps the most unusual history. Following withdrawal in 1963, the locomotive was sold to the Sadler Rail Coach company based at Droxford, Hampshire on the disused Meon Valley Railway. It was used on occasion between the Droxford and Wickham stations on that line. Subsequently it was sold to the Portsmouth-based Brickwoods brewery in the spring of 1966. The brewery wanted it for use outside a new public house to be opened on Hayling Island named The Hayling Billy. The engine was displayed there for a number of years, becoming locally famous, before being donated to the Isle of Wight Steam Railway in 1979. Main line operation None of the preserved members of the class has been restored to full main line running condition. Some consideration was given to doing so during the restoration of No. 62 Martello in the early years of the 21st century, in order to facilitate the appearance of the engine at open days and exhibitions in an operational condition; however the costs involved led to the idea being abandoned. Prior to the end of steam and the banning of steam engines from the national network in 1968, No. 55 Stepney worked two special trains over the metals of the Southern Region. The first trip ran on 21 October 1962 and saw No. 55 double-head with LSWR Adams radial tank No. 488 on the Haywards Heath to Horsted Keynes and return section of a rail tour from London Victoria to the Bluebell Railway. The second train ran from Brighton to Horsted Keynes on 27 October 1963 for members of the Bluebell Railway Preservation Society, which saw the locomotive double-head with another former LB&SCR locomotive, E4 No. 473 Birch Grove, and was run to mark
