Chicago, Indianapolis & Louisville / Louisville, New Albany & Chicago 4-6-0 "Ten-Wheeler" Locomotives in 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 Rail Data Exchange. 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 (Locobase 8303)

Data from CI&L 1 - 1940 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 4235, 4238-4240 in January 1891.

Among the Monon's 19th Century Ten-wheelers, this quartet seems to have been the only class built as mixed-traffic locomotives.

Perhaps surprisingly, the Monon installed a superheater and 51" drivers in 1922-1923; see Locobase 8300.


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 Rail Data Exchange.

The Ten-wheeler never featured as a pure passenger engine on the Monon, although the original design's 65" drvier diameters suggest an ability to keep to a schedule. (Locobase 8303).

After thirty years in service, the Monon's shops made over the class considerably, including fitting G-2s with the much smaller drivers shown in the specifications at the same time they reconfigured the boiler to hold a usefully scaled superheater. The first four had Southern gear, the last Walschaert (the single difference represented by the G-2-B designation.). The road retained its 10" (254 mm) 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 Rail Data Exchange. Works numbers were 2655-2656, 2658 in November 1880; 2695-2696 in February; and 2791-2794, 2803 in August,

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 (124) 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 Rail Data Exchange. Works numbers were 4235, 4283, 4290, 4294-4295

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 16597)

Data from CI&L 1 - 1940 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 4235, 4238-4240 in January 1891.

Most of the Monon's Ten-wheelers had been built as low-drivered freight haulers. But when the railway ordered a pair of 4-6-0s ten years after the most recent set, they delievered a turn-of-the century design that followed the trend toward taller drivers. They also had more cylinder volume, a higher boiler pressure, larger grate and boiler..
