Cheboygan & Presque Isle 2-6-0 "Mogul" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 101 (Locobase 13899)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 41, p. 44. (Thanks to Gretchen Toshach, whose 31 January 2014 email supplied additional information on the C&PI Works number was 33406 in May 1909.

Cheboygan county in Michigan is bounded on the north by Lake Huron and on the east by Presque Isle county. Locobase had not been able to determine whether the C & PI ever actually operated under that names and suspected it soon became part of the Detroit & Mackinac. Gretchen Toshach explains what the mission of this short-lived railroad:

"The railroad was built and owned by my grandfather, M. D. Olds of Cheboygan. It was a standard gaage logging railroad. It was built specifically to harvest hemlock bark after a huge fire in the area. Logging operations began in late 1909 and continued into 1912 when the harvest was done and the rails were taken up. He sold the bark back to Phister and Vogel Tanning Co, which had sold him the property in the first place."

About the 101, Locobase rests on the firmer ground of Gene Connelly's master list of Baldwin production. After the C&PI was taken up in 1912, the 101 wound up on the books of locomotive rebuilder/reseller Southern Iron & Equipment.

SI & E almost immediately sold the engine to the 11-mile Evansville, Suburban & Newburgh, which rebuilt it with 54" drivers and gave it road number 7. This electric interurban line also moved freight and had several steam locomotives for motive power.

The ES & N closed its passenger service in the early 1930s, but maintained freight service into the 1940s.
