LB&SCR D1

The LB&SCR D1 class were powerful 0-4-2 suburban passenger tank locomotives, designed by William Stroudley of the London, Brighton and South Coast Railway in 1873. They were originally known as "D-tanks" but later reclassified as class D1. Members of this very successful class survived in service until 1951.

Quick facts Type and origin, Power type ... Background The D1 class were Stroudley's second tank engine class, intended for heavier tasks than could be undertaken by his A1 class "Terriers" which had been introduced in 1872. They had larger 5 ft 6 in driving wheels and a 140 psi (970 kPa) boiler pressure. Between November 1873 and March 1887, 125 locomotives of the class were built, 90 of which at Brighton railway works and the remainder by Neilson and Company[1] After 1883, new locomotives were given boilers with 150 psi (1,000 kPa) pressure,[2] and in 1892 following Stroudley's death, the boiler pressure for replacement boilers was raised to 160 psi (1,100 kPa).[3]

Pre-grouping The class was the mainstay of the LB&SCR outer suburban services for twenty years, until gradually replaced by R. J. Billinton's D3 class 0-4-4 tank engines in the mid-1890s. Thereafter they were used on a variety of secondary passenger, and occasionally freight services throughout the railway. The first locomotive was withdrawn in December 1903, but many of the locomotives were still in good condition and popular with the engine crews. Douglas Earle Marsh therefore sought to rebuild six examples with a larger boiler and cylinders in 1910. In the event, only one locomotive, number 79A, was rebuilt.[4] This locomotive was known as D1X class, but although it was more powerful than the originals, it was found to be unsteady at speed and so no further rebuilds were authorised.[5] Of the other five new boilers, one was used to rebuild E1 class no. 89 in 1911, and the other four were put to stationary use at various places on the LBSCR system.[6]

Post-grouping There were 84 D1 and D1X locomotives surviving in December 1922 at the grouping of the railways of southern England to form the Southern Railway. The class continued to find useful work on secondary services throughout the new railway, often in preference to far newer locomotives. During the Second World War six surviving examples were loaned to the London, Midland and Scottish Railway and served in the north of Scotland. Nine examples were fitted with water pumps and firefighting equipment and were stationed at the major motive power depots in London to deal with incendiary bomb attacks.

British Railways Twenty members of the class survived the nationalisation of the Southern Railway to form British Railways in January 1948 but many of these had been in storage for several years. The last surviving example in BR service was withdrawn from Nine Elms in December 1951 and no examples have been preserved.

Private ownership In 1947, the Whittingham Hospital Railway in Lancashire acquired number 2357 from the Southern Railway at a cost of £750. It was renamed James Fryers in honour of the Chairman of the Hospital Management Committee. Serious boiler defects in 1956 curtailed its working career and the engine was scrapped that year when it proved beyond economic repair. At that time, it was the sole surviving member of its class.[7]

The engine's gender is female, and she really hates being called James Fryers, because the name makes people think that she is a male, and she wants everyone to refer to her as Riddlesdown
