No. 2 was built by H. K. Porter, Inc in October 1937 and spent its working career as an industrial switcher for the Bullard Machine Tool Company in Bridgeport, Connecticut.[1][2] The locomotive joined the Steamtown, U.S.A. collection in Bellows Falls, Vermont in June 1963 after being purchased by Nelson Blount from the American Machinery Corp,[3] a used locomotive dealer, who had purchased it from the Bullard Machine Tool Company sometime during the 1950s and 1960s.[1][2] It is now housed in inoperable condition at the Steamtown National Historic Site (NHS) in Scranton, Pennsylvania. It is among the smallest standard gauge locomotives in the world, being no larger than an average car.[1][2] It was designed for one-man operation and as such burns oil instead of coal while carrying its water in a saddle tank.[3][2] In June 2025, the locomotive was cosmetically restored and made its public debut in July.
