This Pacific & Eastern road was NOT the better-known P&E headquartered in Medford, Ore, but an 8-mile (12.9-km) logging road based in Raymond, Wash and operating from 1907-1913. Soon after it took delivery of this logging Prairie, the P&E was reorganized as the Puget Sound & Willapa Harbor Railway. It ultimately reached from the Raymond tidal flats on the Willapa Harbor eastward through Chehalis and Centralia to the Milwaukee Road's junction at Maytown.
For some reason, the PS&WH renumbered the 102 as 5100, which the Milwaukee Road retained when it took over the line in December 1920. Seven years later, the Milwaukee sold the 5100 to Cascade Timber of Kangley, Wash. In 1939, the CT's line was abandoned and the 5100 passed on to Pacific States Lumber Company
