2 is a small 0-4-0ST steam tank locomotive which is preserved at the Steamtown National Historic Site.

2 was built by H. K. Porter, Inc in October 1937 and spent its working life as an industrial switcher for the Bullard Machine Tool Company in Bridgeport, Connecticut.

[1] 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,[2] a used locomotive dealer, who had purchased it from the Bullard Machine Tool Company sometime during the 1950s and 1960s.

[1] It is now housed in inoperable condition at the Steamtown National Historic Site in Scranton, Pennsylvania.

[1] It was designed for one-man operation and as such burns oil instead of coal while carrying its water in a saddletank.
