 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.

Background

The D1 class were Stroudley's second tank engine class, intended for heavier tasks than could be undertaken by his A1 class
LB&SCR A1 Class
The London, Brighton and South Coast Railway A1 Class is an English class of 0-6-0T steam locomotive. Designed by William Stroudley, 50 members of the class were built in 1872 and between 1874 and 1880, all at Brighton Works. The class have received several nicknames, initially being known as...

 "Terriers" which had been introduced in 1872. They had larger 5' 6" coupled wheels and a 140 psi (965.3 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 & Co. After 1883, new locomotives were given boilers with 150 psi (1,034.2 kPa) pressure, and in 1892 following Stroudley's death, the boiler pressure for replacement boilers was raised to 160 psi (1,103.2 kPa).

. 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 depot

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.
