Classification
Classification is complex. The NER initially classified these locomotives "M1" while a variant (with compound expansion) was classified "M". The compound was later re-classified "3CC" and the "M1" was re-classified "M".
Under LNER ownership the "M" (formerly "M1") became LNER Class D17/1 and the "3CC" (formerly "M") became LNER Class D19.
This table summarises LNER classes D17, D18 and D19, which were all very similar:
| Original NER class | New NER class | LNER Class | Cylinders | Driving wheels |
|---|---|---|---|---|
| M1 | M | D17/1 | (2) 19" x 26" | 7' 1¼" |
| Q | - | D17/2 | (2) 19½" x 26" | 7' 1¼" |
| Q1 | - | D18 | (2) 19½" x 26" | 7' 7¼" |
| M | 3CC | D19 | HP (1) 19" x 26" LP (2) 20" x 24" |
7' 1¼" |
- HP = high pressure cylinder, LP = low pressure cylinders
Withdrawal
The last two D17/1s were withdrawn in 1945. Number 1629 was scrapped but number 1621 was saved for preservation.
No D17/1s passed into British Railways ownership. Two D17/2s did (BR numbers 62111 and 62112) but they were withdrawn in February 1948.
Preservation
- D17/1 number 1621 is preserved at the National Railway Museum.
