British Rail Standard class 3

The BR Standard class 3 tender locomotive was a 2-6-0 mixed traffic design that differed somewhat from the other standard designs. They were built at Swindon, and so it's not surprising that their boiler was based on the GWR No. 2 standard boiler used on the Large Prairie and class 5600. But they still had many influences from LMS locomotives, like the chassis and other parts based on the LMS Ivatt class 4. Due to the presence of the Standard classes 2 and 4, only 20 of the class 3 were built. The first one was withdrawn in 1965 and all others followed in 1966 and 1967.
