I read with interest your section on the North British/MAN 330hp 0-4-0DH shunters D2900-13. Your data rightly shows them allocated to Devons Road but in reality they spent their working lives shunting at Poplar Docks/Blackwall yards. They used to thunder up the Harrow Lane incline that took the line over that which led to Poplar Station (now DLR All Saints) and the noise of the diesel hydraulic at full whack was impressive. Loud enough to act as a wake up call to me on school mornings as I lived backing on the Midland coal depot just a bit further along! The site where they were always to be seen is now the DLF main depot.
