They entered Midland Railway stock in 1912. The Midland gave them the power classification 2P, and renumbered them 2158–2175. They subsequently entered London, Midland and Scottish Railway stock in 1923. They retained their ex-Midland Railway numbers until 1930 when they were renumbered 2092–2109.

Number 2105 was withdrawn in 1947, and the remaining seventeen of these entered British Railways stock in 1948, and were to be renumbered 41910–41926, but only three (41922, 41923 and 41925) survived to carry their new numbers. The last was withdrawn in 1953. None was preserved.
