On the GNR, both varieties were classified J23, but the LNER divided them into J51 with smaller boilers, and J50 with larger boilers. [5] They were unsuperheated, although the prototype J51 (3167) was fitted with a 16-element Robinson superheater as a trial. The savings from this were small, 3.7%, and not considered worthwhile.

The newly-formed LNER adopted the J50 as a Group Standard design, and between 1926 and 1939 a total of 52 more J50s were built. The Group Standard J50s had a slightly different cab profile to fit the Composite Gauge.

The J50/1 class consisted of ten J51 engines of 1913-14. These were smaller Gresley GNR locomotives which were rebuilt from 1929 as J50 engines. The J50/2 was a Gresley design for the GNR. They were built in 1914-24 and also incorporated twenty rebuilt from J51 locomotives between 1915 and 1922. The J50/3 was a post grouping development of the ...

On the GNR, both varieties were classified J23, but the LNER divided them into J51 with smaller boilers, and J50 with larger boilers. The LNER continued the construction of Class J50, building a further 62 up to 1939, only the first ten of which were given secondhand boilers.

From 1900, the GNR adopted a system of classification based on a locomotive's wheel arrangemenent (using the Whyte Notation), with each arrangement being represented by a letter. Initially, the letters A to J were allocated in ascending order of driving axles and descending order of leading axles.

The LNER inherited over 1,000 examples (14% of the total) from all seven constituents – a total exceeded only by the 0-6-0 tender type. 0-6-0Ts were particularly popular with the Great Northern Railway (GNR) and the Great Eastern Railway (GER).

Aug 25, 2011 · Intended for the West Riding, the initial J50 and J51 allocations were to Ardsley, Bradford, and Copley Hill. These engines were used for local goods and coal workings, with shunting at intermediate yards. There were also used for shunting the larger West Riding marshalling yards.

No. 68911/10 was a 'class J50' 0-6-0T engine designed by N. Gresley, built at the Doncaster Works and new to the Great Northern Railway (GNR) in Jun 1919 carrying No. 212.

Jun 9, 2023 · Ex-GNR LNER J50 0-6-0T 68914 - now 'Departmental Locomotive No 11 ' - at Doncaster works, on a sunny day in June 1964, with BR AL2 E3047 in the background. The J50 had entered service in 1919, and was withdrawn in November 1960, and entered departmental service in February 1961.

Forty were built by the Great Northern Railway (GNR) between 1913 and 1922, with a further 62 being added by the London and North Eastern Railway (LNER) between 1924 and 1939. They were given the nickname "Submarines" due to their long tanks. 1.
