Bachmann Branchline 32-355 Standard class 4MT 2-6-4 tank 80136 in BR black with early emblem

Introduced originally in 1951, the Class 4 2-6-6T's were the most numerous of all Standard tank locomotives, a total of 155 being constructed over a six yera period. Out of the total number, 130 were built at Brighton works with the remainder-ácoming from Derby and Doncaster. Numbered in the 80000 series, the Britrish Railways Standard design owes its ancestry to the basically similar locomotives developed for the-áLMS by Stanier and Faiburn between 1935 and 1948. Although classified 'mixed traffic' by BR, the engines were-ámore suited to their role as a passenger tank for use on long distance suburban trains, although they could easily handle short distance freight workings. They proved themselves to-ábe fast, reliable machines and became popular with their crews. Although the first locomotive-áwas withdrawn as early as 1962, general scrapping did not commence until 1964, with some examples on BR (SR) lasting until the end of steam power late in 1967.
