Numbering

The GNR numbered them 1009A, 1010, 1013–1020 and 1501–1550. 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).
