The British Railways Standard Class 4 tank is a class of steam locomotive, one of the BR standard classes built during the 1950s. They were used primarily on commuter and outer suburban services. They were capable of reaching speeds of 75 mph (121 km/h). [1]

The most recent addition to the Mid Hants Railway fleet was acquired from Glamorgan Council in exchange for our ex-Bricklayers Arms turntable which they intend to install at Barry as part of their plan to turn it into a mainline destination.

80079 is a BR British Rail or British Railways Standard Class 4 2-6-4T tank engine designed by R.A. Riddles Robert Arthur "Robin" Riddles, Member of the Railway Executive for Mechanical and Electrical Engineering responsible for the design of the British Rail Standard Class locomotives.

One of the most successful of these Riddles designs were the Class 4, 2-6-4 Tank locomotives of which 155 were built at Brighton and Derby from 1951 to 1957.

A series of 155 Class 4 tank locomotives was ordered, based largely on the ex-LMS Fairburn 2-6-4T engines with some modifications. The history of this class could be tracked back through to the LMS/BR Class 4 2-6-4T locomotives dating to the original Fowler design in 1927. Design work was done at Brighton, with the overall programme

These locomotives were designed for cross-country and secondary passenger work. They are a smaller version of the Standard class 5 73000 locomotives and as they are weigh lighter they had almost universal route availability over main and secondary routes throughout Britain.

The British Railways Standard Class 4 4-6-0 is a class of steam locomotives, 80 of which were built during the 1950s. Six have been preserved. 75076 with a double chimney and BR1B type tender. The class was introduced in 1951.

Designed by R.A. Riddles the BR Standard 4 Class was first introduced in 1951. With 155 engines built, and allocated to all areas with the exception of the Western Region, the Standard 4 was an ever present feature on freight and suburban trains.

These locomotives were built for suburban and semi-express passenger work. They were based on the 42050 series of the LMS Stanier and Fairburn 2-6-4T locomotives, but with the tank sides, cab and bunker sloping inwards to conform with the loading gauge.

The 76000 class were the only standard tender engine class to be completely withdrawn from service by end of 1967 apart from the 2-8-0 Austerity locomotives built between 1943 and 1946. 76097 was only in service from September 1957 until July 1964.
