These locomotives were built as a tender version of the 82000 3MT class, designed for working on virtually any main or secondary line throughout Britain. They had a boiler based on the GWR Swindon boiler fitted to the GWR 5101 and 5600 class locomotives. The chassis were closely based on and sharing a number of parts with the LMS Ivatt 43000 class 4.

Both the tender version (77000 class) and tank version (82000 class) were all built at Swindon. The tank engine version was introduced in April 1952 whilst the first tender engines was completed in February 1954. The tank engines were more numerous with 45 being built compared to only 20 of the tender engines. There had been plans to build a further five members of the 77000 class engines but the order was later cancelled.

Unlike a number of the larger BR Standards the exhaust steam manifold within the smokebox saddle was a steel fabrication that was part of the welded saddle. In a number of the large BR standards (BR Standard class 6 and class 7 engines) the exhaust steam manifold was a steel casting welded into the saddle during manufacture.

They were fitted with BR2A 3,500 gallon tenders.
