Billerica & Bedford / Bucksport & Bangor 0-4-4 "Forney" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class Bucksport (Locobase 11761)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 9, p. 196. Baldwin works number was 4818 in October 1879. See the excellent Tap Lines site ([]) for Don Hensley, "The Orange Belt Railway".

An unusual feature of this adhesion-first tank was the relatively wide and short firebox. In fact, Locobase wonders if the specs inadvertently traded the width for the length and that the width should read 24 11/16" and the length 47 5/8"

At the time of its opening in 1873, the B & B was the only railroad in Maine's Hancock county; it served the ice-free port of Bucksport, 18 miles from Bangor. The line remained independent for about 9 years before its foreclosure and reorganization as the Eastern Maine Railroad Company. The EMRC leased the B & B to the Maine Central in 1883.

The MC widened the rail gauge to standard. Eastern Maine retained the narrow gaugers, later selling the skinny-gauge snowbirds to the Orange Belt Railway. The 142-mile OBR served the St Petersburg, Florida area. The OBR standardized in 1894 and changed its name to Sanford & Saint Petersburg; Gene Connelly's Baldwin list doesn't record what happened to the

Class Puck (Locobase 1002)

Data from [] (reviewed 13 Feb 2004). # 3 had 48" drivers. Works numbers were 1251 and 1261.

Operated on the largest 2-foot gauge railroad in US, the SR&RL in Maine. A Hinkley summary supplied by Allen Stanley in March 2004.
