Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 19, p. 29, p. 212,. Works numbes were 14449 in September 1895 and 29575 in November 1906.
B&T's #3 used more cylinder volume, a bigger boiler, firebox, and grate than the Zealand Valley and East Branch & Lincoln engines. It was intended to scale steep grades of 264 ft per mile (5 %) and negotiate curves of 32 to 38 degrees. The 5 duplicated the Berlin (#3), but put 68,000 lb (30,844 kg) on the drivers, 100,00 lb (45,359 kg) on all four axles.
It's not clear from Gene Connelly's notes when the EB&L actually took delivery of the 5. Baldwin's specs give the EB&L as first operator. On the other hand, Connelly gives us Zealand Valley, which then sold the 5 to EB&L. Photos show a long-wheelbase, large saddle tank, three equal-sized domes consisting of 2 sand domes flanking a steam dome, and a long smokebox ahead of the tank.
In 1947, the Franconia Paper Company took possession of the 5. Eventually the FPC donated the engine as a display at Loon Mountain Ski area.

This was either a relatively large tank or a standard 4-4-0 with its auxiliary trucks relocated to allow easier movement in either direction. The railroad -- also known as the Success Pond Railroad -- was based in Mason, Maine, but remianed open for only 5 years. When the B & T closed in 1900, the 2 went to Buffalo Union Furnace Company of Buffalo, New York.
