Builder info from B.Rumary, 25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND and Jeremy Lambert as supplied by Allen Stanley in March 2004. Although there's no exact match in the data, Locobase thinks the pair delivered as Louisville, New Albany & Chicago, 111-112 (works #2767-2768) in June 1897 might be the actual locomotives. The Monon's numbers were 80-81 at some future date.
The Monon was the Chicago, Indianapolis and Louisville Railway. The cab sported a clerestory which combined with the engine's tall domes and thin smokepipe gave the impression of a nearly square profile.
Locobase doesn't know much about this brace of Eight-wheelers. There may have been more than two. The design is typical for the early 1890s in its narrow firebox and steam dome over the crown sheet.
Locobase doesn't know much about this early (for the Monon) Eight-wheeler.
Locobase doesn't know much about this early (for the Monon) Eight-wheeler.
According to the diagram, the C I & L rebuilt two Eight-wheelers (supplied originally by Brooks) in 1924. The one shown here is the saturated-steam variant. See Locobase 8295 for the superheated 81.
Locobase 8294 describes the saturated-boiler version of this pair of locomotives rebuilt by the C I & L. The high-pitched boiler sacrificed 136 tubes in favor of 22 flues for a modest amount of superheat.
