Erstwhile Metropolitan Railway L2 class 2-6-4T in its LNER guise as no. 6158 in charge of an Aylebury bound passenger servioce on the Met. & LNE Joint Railway near Chalfont & Latimer in October 1942. I the date is correct and I belive it is then this is a rare wartime picture. 6158 Spent its entire career based at Neasden and would be withdrawn at the BR(E) shed in October 1948 never having been renumbered as BR 69070.
