Class Details by Steve Llanso of Sweat House Media

Class D / F-5 (Locobase 11129)

Data from T, St L & W's 1911 and 1924 locomotive diagram books supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works number and road numbers for the original TStL&KC delivery did not line up, as the following table shows:

Class F-6 (Locobase 6715)

Data from TStL&W 1911 Locomotive Diagram supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Volume 23, p. 245.

The locomotives' original tenders carried 4,000 US gallons (15,140 litres) of water and weighed 80,000 lb (36,287 kg) fully loaded.

When the Nickel Plate took over the TSt&W in June 1923, they renumbered the class 820-825 and operated them for almost six years longer before retiring the class in January 1929.

Class H (Locobase 2626)

Data from Catalogue Descriptive of Simple and Compound Locomotives built by Brooks Locomotive Works, Dunkirk, NY (Buffalo, NY: Matthew-Northrup Company, 1899).

Builder info from B.Rumary, 25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND and Jeremy Lambert as supplied by Allen Stanley in March 2004.

Works numbers were 1629-1633 in March 1890. Rumary-Lambert credit the class with 19" cylinders, which they may have received some time after their initial delivery.

Low-drivered light Mogul for the Nickel Plate, as the New York, Chicago, and St. Louis was known. The class was renumbered in 1910 with retirements beginning only a few years later in 1913 (2). Two more were withdrawn in 1914 and 219 was scrapped in June 1916.
