British Railways reclassified both of them F5 on 22 December 1948. On 1 January 1923 the majority of the class were allocated to Stratford Engine Shed and were employed on suburban traffic in East London on the lines out of Fenchurch Street and Liverpool Street.

Thirty of the M15 locomotives were rebuilt between 1911 and 1920 with higher pressure boilers to become LNER Class F5. Most of the F4s and F5s spent their lives working the London suburban services, until being replaced by N7 s.

The Holden F5 Steam Locomotive Trust, formed in 2003, is constructing a replica of the Great Eastern Railway’s M15r (latterly LNER F5) Class of locomotives, designed by James Holden and an improvement upon members of the earlier M15 (LNER F4) Class introduced by Thomas William Worsdell.

The LNER class F5 engines were rebuilt from 1911 onwards from F4 class locomotives built at Stratford between 1903 and 1909. These engines had higher pressure boilers and as with the class F3 tanks there was a lot of variation in the boiler mountings (chimneys, domes and …

When the GER was amalgamated into the LNER in 1923 they were classified F6 (instead of F5). It wasn't until 22 December 1948 that the "twins", now numbered 67218 and 7219 respectively, were correctly reclassified into the F5 category. 7219 received her British Railways number in November 1949 after a general repair at Stratford.

After the grouping of 1923 the M15/M15R became LNER class F4 and F5 respectively, although two of the M15R locomotives had cabs with side windows like the larger G69 class and were designated F6 7789 & 7790 (renumbered 7218 & 7219 in 1946).

The 2-4-2T was adopted by many companies for local passenger work (and in at least one case for semi-fast duties). The LNER inherited 341 at Grouping (1923), and did not build any of its own. Due to the large numbers inherited from the Great Eastern Railway (GER), they outnumbered all other four-coupled tank designs.

The Great Eastern Railway M15r Class (latterly LNER Class F5) 2-4-2T was designed by James Holden and was a improvement upon members of the earlier M15 (LNER F4) Class 2-4-2T introduced by Thomas William Worsdell.

Jun 6, 2008 · The GER Class M15 was a class of 160 2-4-2T steam locomotives designed by Thomas William Worsdell and built for the Great Eastern Railway between 1884 and 1909. The original (F4) class of locomotives were fitted with Joy …
