�Jubilee� No.45721 Impregnable on a southbound express at Brinklow is in the BR lined black which it carried from March 1949 until October 1952 when it was repainted in green. This was one of a number of the later members of the class shedded at Bushbury for use on the Wolverhampton-Euston services, although it moved away to Crewe North in October 1949 and then to Edge Hill in February 1950. No.45721 received the Fowler 3,500 gallon tender in August 1948 from �Patriot� No.45523 when that engine took the �Jubilee�s 4,000 gallon tender on rebuilding with a taper boiler.
