LNWR Class G1 Type and origin Power type Steam
The London and North Western Railway (LNWR) Class G1 was a class of 0-8-0 steam locomotives . It was a superheated version of the LNWR Class G . Engines were either built new or rebuilt from previous classes.
Numbering
Numbering is somewhat complicated. The LNWR used a numbering system based on the lowest available number, with the result the the numbers were scattered through the stock book. The LMS renumbered the engines into a more logical series, however they also then continued to rebuild engines, which retained their numbers originally assigned by the LMS.
