|V - E - T - D|
The LMS Stanier Class 5 is a type of 4-6-0 steam locomotive which was built between 1934 and 1951 with several variations. The locomotive is almost universally known as the Black Five, due to their black color scheme and their power class of 5MT.
18 are preserved, with only about 2 or 3 operating steam excursions.
They were a mixed traffic locomotive, a "do-anything go-anywhere" type, designed by William Stanier, who had previously been with the GWR. In his early LMS days, he designed his Stanier Mogul 2-6-0 in which he experimented with the GWR "School" Class of thought on locomotive design.
A number of details in this design he would never use again realising the superiority of details not used on the GWR. Stanier realised that there was a need for larger locomotives. These were to be the LMS's version of the GWR Halls but not a copy, as the Hall was too wide to run most places in Britain. They shared similar cylinder arrangement (two outside), internal boiler design and size and 6 foot driving wheel diameters.
In their early days, the locomotives were known as the "Black Staniers" from their black livery, in contrast to Stanier's other class of 4-6-0, the LMS Stanier Jubilee Class, which were painted crimson (and known until April 1935 as the "Red Staniers"). Later on, the nickname of the former became "Black Five", the number referring to the power classification. This was originally 5P5F, but from 1940 was shown on cabsides as the simple figure 5.
The locomotives weighed in at 72.2 or 75 long tons. The driving wheels were 72 in (1.8 m) diameter and the carrying wheels were 39.5 in (1 m) diameter. The locomotives had 2 cylinders which were feed from a superheater. The boiler produced 225 psi of pressure, and the fire grate was 27.75 or 28.5 ft2 (2.57 or 2.65 m2). The locomotive made 25,455 lbf of tractive effort.
The tender could carry 4000 imperial gallons of water, and 9 long tons of coal.
