Numbering

The GNR numbered them 1009, 1010, 1013–1020 and 1501–1550. In 1921, no. 1009 was renumbered 1009A, since its number was required for a new Class H4 2-6-0.^[1] All passed to the London and North Eastern Railway in 1923, who renumbered them by adding 3000 to their GNR number.

In the post World War II renumbering scheme, the remaining 50 locomotives were renumbered 7350–7399.

In 1948, the remaining 49 locomotives passed to British Railways, who renumbered them by prefixing a 6 to their LNER number (i.e. 67350–67399).
