The London and North Western Railway (LNWR) Class G1 was a class of 0-8-0 steam locomotives. Superheated version of the LNWR Class G.

Engines were either built from new or rebuilt from previous classes:

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.

There is something wrong with this table:

Source Dates (re)built Total (re)built (Re)built by LNWR LNWR No(s) Rebuilt by LMS LMS No(s) Notes
Prototype Class G 1912 1 1 2653 0 9154
New construction 1912-1918 170 170 ... 0 9155-9334
Class B 1917-1927 91 46 ? 45 ?
Class E 1917-1924 18 12 ... 6 ...
Class F 1921-1924 10 6 1036, 1038, 2570, 2114, 2573, 1369 4 initially: 9349/65/7/72/3/86.
Class D 1925-1934 63 0 n/a 63 9002-64
Class C 1925-1927 5 0 n/a 5 8953/4/62/4/6
Class G ? 91 0 n/a 91 9077-9144
Total: 1912-1934 449 235 see above 214 see above

Some were rebuilt back from Class G2a to Class G1 as they passed through heavy overhaul and received lower pressure boilers.

Confused yet?
