J.B. Lyon Co. New York (State), 1919 v.9 no.14 pt.1 , the BR & P was planning to buy 15 of these for just over $1 million.
Other than the Triplexes built for the Erie and the Virginian and the latter's AE 2-10-10-2s (Locobase 417), these Mallet compounds had the most total cylinder volume of any built-from-scratch locomotive.
(The Buffalo, Rochester & Pittsburgh was an independent railroad until bought out by the B&O in 1932. In B&O service, these Mallets were known as EE-2. )
