Chicago, Indianapolis & Louisville / Louisville, New Albany & Chicago 4-6-0 "Ten-wheeler" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 36/G-1 (Locobase 8299)

Data from CI&L 8 - 1941 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Volume 18, p. 218. Works number was 13514 in June 1893.

A low-drivered freighter from the early 1890s, the safety valve setting for this engine displayed two unusual qualities: 1) Except for Vauclain compounds, 180 psi was a higher setting than most US locomotives used in the early 1890s, and 2) The Monon apparently never reduced that setting. Baldwin's specs gave the original heating surface area as 1,653 sq ft (153.57 sq m). They also warned "Last consol engines [Locobase 8306]gave trouble with leaky mud rings. Be particular to have these tight."

When the shops refitted the 100 in 1924, they installed 51" (1,295 mm) drivers, which raised starting tractive effort to 23,400 lb (10,614 kg). Otherwise apparently unchanged from its original configuration, the lone Ten-wheeler was scrapped in October 1936.

Class G-2-A/-B (Locobase 8300)

Data from CI&L 8 - 1941 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

Apparently the Ten-wheeler never featured as a passenger engine on the Monon. Instead, they fielded low-drivered freight engines like this quintet. The first 4 had Southern gear, the last Walschaert (the single difference represented by the G-2-B designation.). In the superheater upgrade performed in 1921-1923, the road retained its 10" piston valves and relatively small grate.

Class G-3/G-4 (Locobase 8301)

Data from CI&L 8 - 1941 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

These Ten-wheelers date from the early days of the C I & L and were relatively ample for the early 1880s (they arrived in 1880-1881). As shown in the diagram, the design had an unusual firebox that may have actually been a Belpaire type. The steam dome rode over the first two driven axles just behind the sand dome. The sketch, which is nicely detailed, illustrates the capped stack that a few US railroads (the ACL, for one) adopted as a signature. The Monon was especially well known this fillip to what was often simply a tapered pipe.

The diagram also notes that several in the class received new boilers, the first (123) in 1897, the last (124) in 1904. Locomotives with 55" drivers were classed G-3; those with 51" drivers were designated G-4.

Class G-5 (Locobase 8302)

Data from CI&L 1 - 1940 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

In the same year that Rogers delivered the Eight-wheeler shown in Locobase 8297, the builder supplied this quintet of Ten-wheelers of very nearly the same power dimensions. The boiler was bigger, of course, as was the adhesion weight. Later on, the single G-5-A (132) had 19" cylinders and was refitted with Southern outside valve gear.

Class G-6 (Locobase 8303)

Data from CI&L 1 - 1940 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

Among the Monon's Ten-wheelers, this pair seems to have been the only class built as a mixed-traffic locomotive. Also, because it came somewhat later, it had more cylinder volume, a higher boiler pressure, larger grate and boiler ...much more of a 20th-Century design.

Drury (1993) states that these had 69" drivers and later were retrofitted with 51" wheels. But the diagram shows 63", a size supported by the diagram's tractive effort figure . The two served the Monon until 1942 and 1948, respectively.
