According to a compilation of Cooke locomotives by B.Rumary (25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND) and supplied to Locobase by Allen Stanley in March 2004, works numbers were 1612-1616 (February 1885) and 1617-1621 (April-May 1885). Their road numbers suggest that they were the first for the M & NW.
Jerry L. Huddleston explains, on http://www.trainweb.org/cgw/history-bin/about_the%20cgw.html (visited 11 August 2004), that the M & NW was the 110-mile predecessor of the Chicago Great Western that opened in 1885 by the "imaginative and energetic Minnesotan, A.B. Stickney". Stickney soon extended the M & NW to Kansas City and Chicago. Two years later, he merged the M & NW with the Chicago, St Paul, & Kansas City (C, St P & KC), which he also owned. Finally, Stickney merged the C, St P & KC with the CGW in 1892.
This class was ordered by and delivered to the M & NW. These were a bit bigger than the later 4-4-0s of this system. Number in the original class isn't known (3 engines left as of 1917).
According to a compilation of Cooke locomotives by B.Rumary (25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND) and supplied to Locobase by Allen Stanley in March 2004, works numbers were 1809-1816 (July 1887). See Locobase 4158 for discussion of the M & NW and its later acquisition by the Chicago Great Western.
Locobase cannot match up this class to any entry in the compilation of Cooke locomotives by B.Rumary (25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND) and supplied to Locobase by Allen Stanley in March 2004.
According to a compilation of Cooke locomotives by B.Rumary (25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND) and supplied to Locobase by Allen Stanley in March 2004, works numbers were 1652-1654 (December 1885) and 1655-74 (April-July 1886).
This substantial order built on the earlier 4-4-0s delivered in 1885, but reduced the size. By the time the 1917 diagrams were published, only two were left in service on the successor Chicago Great Western.
According to a compilation of Cooke locomotives by B.Rumary (25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND) and supplied to Locobase by Allen Stanley in March 2004, works numbers were 1939-1943 (November1888). Four years later the C, St P & KC would be merged with the Chicago Great Western.
