[7] A final locomotive was built by Beardmore in February 1924, which was displayed at the British Empire Exhibition that year; the LMS bought it in November 1924, and numbered it 5845.

[9] The arrival of Stanier 4-6-0s also displaced them from their work so withdrawals which had started in 1933 meant that by 1939 only 22 remained.

Withdrawals were suspended during World War II, but recommenced in 1944, and just six were inherited by British Railways in 1948.

[10] In March 1948, the four then remaining (25648 Queen of the Belgians, 25673 Lusitania, 25752 and 25787) were allocated the numbers 58000–3, but were all withdrawn before renumbering could be applied.

[13] Variations included Belpaire fireboxes[2] from 1924,[citation needed] and outside Walschaerts valve gear was fitted to four engines in 1923–4 and also to no.
