Estate Monymusk 0-4-2 Locomotives in Jamaica
Class Details by Steve Llanso of Sweat House Media
Class 1 (Locobase 14502)
Data from DeGolyer, Volume 63, pp. 328. See also a history of the Monymusk Estate at [
] . Works numbers were 47527-47528 in January 1918.
Monymusk Estate, located on the south side of Jamaica in Clarendon Parish, opened its sugar operations in 1901 under the direction of its owner Colonel CJ Ward. In 1916, the estate of CJ Ward sold the business to the Lindo Brothers.
The new owners told Baldwin that the typical train for these wood-burning plantation tanks would consist of 30 short tons of cane cars. Given that the tare weight of each car was 1,120 lb and the load was 2,240 lb, this works out to 20 cars. The cars were coupled "with just a good strong hook, 15"[381 mm] above the rail. Cars need no buffers as the long members extend 12" or 14" beyond the cross members." Moreover, there were no curves or interlockings. A Radley & Hunter balloon stack arrested sparks.
