Wabash No. 587 was a 2-6-0 "Mogul" type steam locomotive it was built in 1899 by the American Locomotive Company's Rhode Island plant, as construction number 3140, for the Wabash Railroad where it worked hauling freight trains.
As Class F-5, it was built as a compound, but by 1917, it was simpled.
It was used on the Keokuk Branch, stabled in the Bluffs, IL, roundhouse with classmates 573 (now preserved) and 576, well after most railroads had eliminated steam power. This was due to the bridges on the line which can only take their weight, as at the time the diesels were too heavy to cross them. Eventually, in 1955, these bridges were strengthened, allowing the diesels to finally banish the Moguls (except for 573, which was donated to the Museum of Transport, St Louis) to the scrap yard.
