Data from "New Locomotive Building," The Railway Age, Vol XXXII, (2 August 1901), p 93.
As competition grew in the Keeweenaw Peninsula (and stole much of the original traffic) the MRR threw out branches in several directions ,e eventually connecting Houghton with Lake Linden and Calumet.
By the time of the purchase of the Consolidations in this entry, the MRR had converted to the standard gauge and was operated in conjunction with the Duluth, South Shore & Atlantic. In 1901, one State of Michigan rport claimed, "The passenger train service furnished by this company, in connection with the Duluth, South Shore & Atlantic trains, from Keweenaw Bay to Ontonagon is all that could be desired. No fencing on this line and apparently no necessity for any. Switches blocked as required by law: crossing signs and plank in good order."
NB: Tube length is an estimate based on the calculation of tube surface area by subtracting reported firebox heating surface from reported total evaporative heating surface
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 39, p. 78. See also a history of Pelahatchie, Mississippi at [], last accessed 4 February 2012. Works number was 36756 in August 1911.
Pelahatchie, Miss had a long history even before Lockwood Lumber set up a sawmill in 1907, but lumber operations spurred rapid growth. To support Lockwood's operations, the company built the MRwy between Pelahatchie and River Hill some 25 miles (40.25 km) away.
A note in the Baldwin specs noted that the 16" (406 mm) stack as delivered was too large for this small Consolidation: "Hereafter furnish a straight stack 16" diameter or a taper stack of smaller diameter." The locomotive's springs were inevitably to be "...amply strong to stand rough track."
The 2 didn't remain with the MRwy for long. It was sold to locomotive rebuilder/reseller Southern Iron & Equipment in 1918. SI & E found a buyer in Mississippi Soft Pine of Canton, which later sold the engine to Lutcher Moore Cypress of St James Parish.
