Sir Henry Fowler’s standard superheated freight design for the MR.  Two engines, Nos. 3835 and 3836, were built in 1911, but construction on a large scale did not commence until 1917.  Between that year and 1922 there appeared Nos. 3837-4026.  In 1924 it was adopted as a standard type by the LMSR, and by 1928 Nos. 4027-4556 had been constructed.  In 1922 five engines had also been built for the Somerset & Dorset Railway, their numbers 57-61.  On the absorption of that line’s engines into LMS stock in 1930 they became Nos. 4557-61, the similarity of the last two figures being entirely coincidental.  After a period of nine years construction was again resumed, Crewe turning out Nos. 4562-76 in 1937, whilst a final batch, Nos. 4577-4606 came out from Derby in 1939-40.

1The ultimate total of 772 engines for one class has rarely been exceeded in this country.

All became BR Nos. 43835-44606, and none was withdrawn until 1954.  Since then a number have been taken out of traffic, but the great majority were still running in 1959.  Although primarily intended for freight work they have been used on all kinds of duties, and were often to be seen on passenger trains.  Apart from differences of tender design and such details as pattern of chimney they have remained unchanged.

Driving wheels – 5’ 3”,  Cylinders – 20”x 26”,  Pressure – 175 lb.,  Tractive effort – 24555 lb.,  Weight – 48 tons 15cwt.,  MR & LMS classification – 4,  BR classification – 4F.
