History
32 of this class were rebuilt from 4-cylinder compound Class B between 1906 and 1917. The outside high-pressure cylinders were removed and the inside low-pressure cylinders were re-used, in their original position, to make a two-cylinder simple expansion engine. The boiler pressure was reduced from 200 psi to 160 psi to keep the tractive effort approximately the same.[1] 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".
