  Further orders saw the class total 83 by 1947 with some built by Walkers Limited. The latter examples were fitted with modified boilers and improved cabs. The early examples were painted prussian blue with the boilers having a natural finish. The latter examples were painted black with red lining. In 1949 all were repainted green with red lining. From 1951 they began to be relegated following the delivery of the BB18¼ class. The first was withdrawn in March 1967, with the last removed from traffic in 1970.
