Construction

Thumb
42421 at Hibel Road station in 1959 - this is one of the Fowler 4MTs with later style side window cabs.

125 examples of the class were built. The last 30 numbered 2395 to 2424 were fitted with side-windows and doors to their cabs.[1] The LMS classified them 4P, BR 4MT. They were the basis for a family of subsequent LMS/BR Class 4 2-6-4T locomotives.[citation needed] The Irish Northern Counties Committee (NCC) Class W 2-6-0 moguls were also strongly influenced by this class, albeit the driving wheel diameter was three inches greater to match the NCC practice.[2]

The cylinder and piston valve design and the setting of the Walschaerts valve gear, allowing a maximum travel of 6+38 inches (16 cm) in full gear, was believed by O. S. Nock to subsequently lead to the "outstanding success" of the class.[2]

Operational use

Most of the class were used on longer-distance commuter trains from stations in London, Manchester and other large towns.[citation needed] A number were allocated to Tebay Motive Power Depot and were used to bank heavy passenger and goods trains up the steep incline to Shap on the LMS West Coast Main Line. Some operated on the long trip from Shrewsbury to Swansea (Victoria).[citation needed] The last two surviving locos were withdrawn from service in 1966. 42389 was hauling the Tring to Euston commuter train that was hit in the rear at Harrow and Wealdstone on 8 October 1952 by a Perth to Euston express, causing the death of 112 people. 42389 was undamaged.[citation needed]

Despite having relatively small 5 feet 9 inches (1.75 m) driving wheels, the class was noted to reach speeds over 80 miles per hour (130 km/h) on outer suburban services to and from Euston.[2]

The LMS numbered the class 2300–2424, BR adding 40000 to their numbers to make them 42300–424.[1]

Preservation and revival

No locos were preserved, but the January 2013 edition of The Railway Magazine reported that a new-build project to recreate a Fowler 2-6-4T was at an initial research stage.[3]

In May 2015, the LMS-Patriot Project announced that after the completion of Patriot Class No. 45551 The Unknown Warrior, it would begin construction on a new-build Fowler 2-6-4T. Similar to the Patriot, it will carry the number of the last member of the class, No. 42424, and be built to main line running standards, though it will only primarily be used on heritage lines.[4]

One of the NCC Class WT locos (No. 4), which drew heavily from the Fowler design and were the last steam locomotives withdrawn in Northern Ireland, is preserved by the Railway Preservation Society of Ireland. In 2024 No. 4 was out of service and being dismantled before overhaul at the RPSI's Whitehead Railway Museum.[5]
