engine. The boiler pressure was reduced from 200 psi to 160 psi to keep the tractive effort approximately the same.
The rebuilt engines retained their old numbers. Additionally, 60 new Gs were built in 1910. The rebuilt engines were easily distinguished from the new builds by having "piano fronts".
Rebuilding
The first of the class, LNWR No. 2653, was rebuilt to
Class G1 in 1912. The remaining 91 engines were inherited by the LMS in 1923. LMS numbers were 9077-9144. The LMS rebuilt them all to
Class G1 between May 1924 and 1937, thus rendering the class extinct.
