The 6400 class was a variation of the 5400 class. Although the 25 engines built in the ‘5400’ class were deemed successful, it was felt that smaller driving wheels would assist in working the hilly South Wales valleys and therefore a new class was introduced with 4 feet 7½ inch drivers.

 2021 2021 class designed by Dean and introduced in 1897. 2062 was rebuilt in 1930 with 5 feet 2 inch driving wheels as an experiment
 5400 5400 class introduced in 1931 which had 5 feet 2 inch driving wheels.
 6400 6400 class introduced in 1932 with 4 feet 7.5 inch driving wheels

After experimenting with number 2062, of the 2021 class, the class of what would become forty locomotives of the ‘6400’ class was produced for auto-working. They all had the modified cabs as found on the latter locomotives of the 5700 class.

The first was withdrawn in 1958 whilst the last stayed in service until December 1964 when 6419 was withdrawn from service at Yeovil Town. 6419 was one of seven withdrawn in 1964 with four being based at Yeovil Town (6400, 6419, 6430 and 6435) at the time. The other three were based at Stourbridge (6424 and 6434) and Gloucester (6412).
