Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 22, p. 53. See also the note in Great Britain's Board of Trade Journal, Volume 33 (6 June 1901). Works numbers were 16566-16575 in March 1899 and 16680-16689 in April.
The BOTJ gave the following summary by Mr J S Brown, Senior Government Inspector of Railways, Burma, of the G's early performance, which was in line with the opinions held by other British railways during a sudden spurt of purchases from American builders:
" The twentieth and last of the Moghal type of engines (' G' class) was erected and placed in running during the half-vear. These American locomotives are now doing fairly well, but gave much trouble at first. They are of heavier build and produce higher bending-moments on all cross-girders of bridges and on small-span bridges than the ' F' class engines. Some of the details showed want of strength, and parts supposed to be of cast steel proved of very inferior metal and workmanship ; alterations and repairs have been required much in excess of what is necessaiy with new locomotives received from British makers."
