New York, Chicago & St Louis / Toledo, St Louis & Kansas City / Toledo, St Louis & Western 4-6-0 "Ten-wheeler" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class E-1 / G-5 (Locobase 12486)

Data from TStL&W 1911 Locomotive Diagram supplied in August 2013 by Allen Stanley from his extensive Raildata collection. Works numbers were 2824-2827 in August 1892, 2846-2850 in January 1893.

This small class lasted only a few years after the Clover Leaf's absorption into the Nickel Plate. Retirements came in 1927 and 1929.


Class E-3/G-7/P-4 (Locobase 12485)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 23, p. 244. Works numbers 18765-18766, 18773 in March 1901, 18978 in May 1901.

43 rolled on 63" drivers. The 42 was one of the very first locomotives to be tested with the Baker-Pilliod valve gear, which would be the only real competitor to the Walschaert gear in the 20th Century.

The design was described in detail in American Engineer and Railroad Journal, Vol 83, No 1 (January 1909) , pp. 32-38. The trials used the original design which in the 40 weighed 3,236 lb (1,468 kg) in all, "of which the moving parts on both sides of the engine give but 1,028 lb [466 kg]."

A comparison between the 42 and sister engine #40, the Baker-equipped 42 burned less coal by several measures.


Class G-6 / P-5 (Locobase 6714)

Data from TStL&W 1 - 1924 Locomotive Diagram supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 3101-3103 in August 1900.

This small class lasted only a few years after the Clover Leaf's absorption into the Nickel Plate. Retirements came in 1927 and 1929.


Class G-8 / P-6 (Locobase 11058)

Data from TStL&W 1 - 1924 Locomotive Diagram supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 30338-30347 in November 1904.

Small, basic Ten-wheeler design that saw very little upgrading in its 25-year career on the Clover Leaf Route. Two were fitted with Baker outside radial valve gear--154 re-entered service on 1 October 1923 and 157 on 1 December.


Class K (Locobase 11127)

Data from Schenectady Locomotive Works, Illustrated Catalogue of Simple and Compound Locomotives (Philadelphia: J B Lippincott, 1897), pp. 94-95. Brook delivered the first five (road # 109-113); works numbers were 2627-2631 in January 1896. Schenectady completed the class (road #114-118); works numbers 4396-4400 in January 1896.

These small freighter Ten-wheelers did not show signs of the impending 20th Century. The design's steam dome perched on the firebox just ahead of the cab, the boiler was nearly straight and slender, the sand dome and bell sat well forward, and the straight, capped stack rose out of an extended smoke box. A small grate and modest boiler pressure set the class firmly in the 1890s.

Because the freight duties were soon monopolized by 2-8-0s and larger, these Ks had only a short career. 293-294 were sold in 1918, the latter on 30 January, but the rest of the class was retired en bloc on 6 December 1920.


Class R (Locobase 13051)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 30, p. 66. Works numbers were 30939 in May 1907; 30988-30990, 31013, 31062 in June.

A sextet of Baldwin passenger Ten-wheelers was pretty uncommon on the NKP. But this set enjoyed a long career, which was lengthened after a 1921-1922 upgrade with superheaters and piston valves.


Class R - superheated (Locobase 6710)

Data from TStL&W 1 - 1924 Locomotive Diagram supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

These Clover Leaf Ten-wheelers stood on relatively tall drivers. Sometime after their purchase, the class was superheated and it's that manifestation that shows in the specs. After their absorption into the Nickel Plate, the class was retired in 1930-1933.


Class R - superheated (Locobase 15627)

Data from NKP 2 - 1944 Locomotive Diagrams supplied in August 2013 by Allen Stanley from his extensive Raildata collection. Brooks works numbers for 156-158 were 53830-53832 in August 1913.

When the Nickel Plate superheated its 1907 Ten-wheelers (Locobase 13051), it did so soon after they arrived on the road. The shops took the usual steps and Brooks duplicated the work with its three new engines.

Outside radial valve gear replaced link motion and now actuated 11" (279 mm) piston valves. 143 small tubes were removed to make room for 22 large flues. The power dimensions changed slightly as the drivers' diameters were increased by an inch (25.4 mm).

153 was retired in June 1933, 150-151 were scrapped in December of the same year. The other six continued to serve throughout World War Two before being sold for scrap in November 1948.
