LMS diesel shunter 7058 was based on an earlier Armstrong Whitworth prototype of 1932, which had been tested by the London, Midland and Scottish Railway. It was initially numbered 7408 and then re-numbered 7058.
It passed to British Railways upon nationalisation in January 1948, which allocated it number 13000. However, it was withdrawn in November 1949 (and scrapped shortly afterwards) before the number had been applied. The number 13000 was then used instead for the first of the British Rail Class 08 shunters.
