Sumpter Valley #100 restoration project

page last updated:  August 15, 2006

On March, 3rd 2001 the first work party was held at Yanke Machine shop to start the restoration work on narrow gauge locomotive #100.  This locomotive is a Whitcomb locomotive built in 1929 (serial #13013).  Locomotive #100 was bought brand new for the Sumpter Valley Railway in 1930.  At some point in time #100 was sold to the J.R. Simplot corporation in Idaho and converted to standard gauge.  According to our current information there was reports of seeing this locomotive in service at the J.R. Simplot plant in Caldwell, Idaho in the mid 1980's.  If anyone has any more detailed or additional information on this locomotive please let me know.

This engine had a wood beam supported cab floor and wood paneled interior, something you do not see in most diesel or gasoline engines!
