Largest 2-ft gauge engine in the US, but not the heaviest. The rear supporting truck was equalized with the drivers. The specs stated that "as many parts as possible [were] to be interchangeable with engines previously built for this road also for the Bridgeton [sic] and Saco River."
Operated on the largest 2-foot gauge railroad in US, the Sandy River & Rangely Lakes in Maine. It was scrapped in August 1936, a little more than a year after the line closed.
The Brecon Mountain Railway in the UK began building a new locomotive from the original Baldwin drawings. As of 2013, construction of the "Sandy River" was described as "well advanced", but still requiring "some years" before it would be completed.
Operated on the largest 2-foot gauge railroad in US, the Sandy River & Rangely Lakes in Maine. Retired in February 1923 and scrapped in September 1935.

Operated on the largest 2-foot gauge railroad in US, the Sandy River & Rangely Lakes in Maine, which offered 4% grades and 20 degree (288 foot/87.8 metre radii) according to the Baldwin specifications. The 24 reverted to the 19's dimensions of 1904 (Locobase 1010). Sold to Robert Sawyer after the SR&RL closed in 1932. Sawyer, although planning to restore the locomotive, suffered either a change of heart or of fortunes, which led to the 24 being scrapped in October 1937.
