Re: oroville *LINK*

On researching Porter NG locomotives, I discovered and interesting reference to two Porter NG used by Utah Construction in building the WP Oroville extension in 1909.
OROVILLE EXTENSION CONSTRUCTION RAILROAD
Utah Construction Company Railroad
Western Pacific Railroad Oroville Division
(CA) Con 3’ 1909 19??
Porter (H.K.) & Company BUILDER’S RECORDS 1878-1951 NP: Robert Lehmuth 2001. locomotive #4253,4254
The Swayne publication referred to is most likely:
Beckstrom, Paul and Braun, David W. THE SWAYNE LUMBER COMPANY: NARROW GAUGE LOGGING IN THE MERRIMAC FOREST. Edmonds WA: Pacific Fast Mail, 1992 175p. maps locomotive/car rosters models bibliography
