This book , which is unique in subject matter, can be bought
reasonably through the various used book dealer conglamorates
(i.e.-Alibris,AddAll,ABE, etc.). Hill rode the Century and
Broadway in continuous cab rides from E to W. The Century,
had Butterfield on a Hudson's right hand seat box on the first
steam leg out of Harmon. The Broadway was hauled by
a K-4s (doubleheaded out of Altoona over the top) for its
passage.
The author did not work for a loco maker, but rather an
oil company. The other story in book work deals with problems
related to developping valve oil to work under high pressures
found on the N&W's family of modern class 'A' and 'Y'
articulateds. If steam, and steam operations at the acme
of their use interest you... this is the most accessible, and
affordable opportunity you will have.
Good-Luck, PJB
