This was the Collett version of the 2800 class. Built 20 years after the last 2800 class locomotive was built. They were slightly heavier with large side-windowed cabs and outside steam pipes. There was a casing on the left hand side of the locomotive on the running plate (looking like a continuous splasher over the wheels) which was to store the fire-irons.
83 locomotives of the 2884 class were built between 1938 and 1941. Those built during the war did not have the side window to the cab, and the side window on the others was plated over. This was to reduce glare as a precaution against air attack. The windows were reinstated after the war.
Twenty of the 2800 and 2884 class locomotives were rebuilt to oil burning during the coal crisis of 1947. They were renumbered in the 4800 series (causing the 4800 class of 0-4-2Ts to be renumbered in the 1400 series). By 1950 they were all converted back to coal burning with their original numbers.
They were so popular with the ex-Great Western crews that the Western Region operating authorities wanted more of the class built after nationalisation in 1948; however, this request was turned down in favour of BR Standard Class 9Fs.
Many of the standard 9F locomotives built in the later part of the 1950s were used to replace 2800 and 2884 class locomotives on the Western region of BR.

The standard 2-10-0s were withdrawn from duty on the Western Region in 1965 (including the last steam locomotive built 92220 Evening Star) but a number were reallocated to depots on the Southern, London Midland and Eastern Regions.

The 2884 class remained in service later that the earlier 2800 class and only reduced significantly in numbers operating at the same time as the Standard 92000 class reduced.
