Rebuilt (M15R) locomotives: F5. Numbers 7789 and 7790 were incorrectly classified F6. 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.

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 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 …

Drawing Nr 21158 is also marked up for class F6 locomotives, i.e. under LNER ownership from 1923. Additionally, this drawing was also marked up in red with specific dimensions for the two ‘hybrid’ M15R (F5) locomotives with the G69 (F6) cabs, i.e. ours – …

The LNER 2-4-2 Locomotives 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.

Mar 28, 2017 · When James Holden added a total of 120 locomotives to the class in 1903 (with production continuing until 1909), he used the Stephenson link motion to reduce fuel consumption. Thirty of the total were converted to a 180-psi boiler in 1911-1920. Those engines were classed F5 by the LNER.
