LNWR Class D - Numbering

Numbering

All Ds were numbered in the 18xx or 25xx series by the LNWR. All passed into LMS ownership in 1923, and the LMS assigned them the numbers 9002-64, sequentially in order of rebuild date.

The LMS rebuilt all of the Ds with the addition of superheating, taking them into Class G1, nicknamed "Super Ds" between 1925 and 1934. Many carried their LNWR numbers until rebuilt for a second time, and the LMS number thereafter. And thus the class was rendered extinct.
