Illinois Central 4-4-0 "American" Type Locomotives

Class 1901 (Locobase 7028)

Data from the IC 1911 Locomotive Data and 1913ca Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

As the IC was turning out Moguls in 1888 (see Locobase 7016), it took the same boiler and grate and made passenger-engine Americans out of the basic design.

Class 1905 (Locobase 7029)

Data from the IC 1911 Locomotive Data and 1913ca Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Much of the IC's 19th-Century locomotive roster consisted of freight or mixed-traffic engines. In this year, however, Brooks provided 25 locomotives in two classes. The more common was the group described in Locobase 7031. The sextet represented here had the tallest drivers by far of any IC engines of the period, of a diameter suitable for true express work.

Class 1912 (Locobase 7031)

Data from the IC 1911 Locomotive Data and 1913ca Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

As noted in Locobase 7029, most of the IC's locomotive roster in the 19th-Century consisted of freight or mixed-traffic locomotives. This relatively numerous class was typical of the railroad.

Class 1930 (Locobase 7032)

Data from the IC 1911 Locomotive Data and 1913ca Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Rogers supplied two sets of Americans to the IC in the last decade of the 19th Century. They seem to have used the same grate, but had different boilers. See Locobase 7033 for the other variant.

Class 1933 (Locobase 7033)

Data from the IC 1911 Locomotive Data and 1913ca Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

This septet had the same running gear and cylinders as the Rogers trio that was delivered to the IC the year before. The firebox was a bit smaller and the boiler had 8 fewer tubes. The difference in tube heating surface doesn't quite compute but both the 1911 listing and the 1913 diagram insist on the numbers given in the specs.

Class 1940 (Locobase 7030)

Data from the IC 1911 Locomotive Data and 1913ca Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

The long wheelbase on these Brooks engines comes from the tradtional placement of the firebox between the driving axles. Given the long span between the leading driving axle and the truck, this engine had a low and overextended profile.

Class 1948 (Locobase 7034)

Data from the IC 1911 Locomotive Data and 1913ca Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Cooke's contribution to the IC's American holding was this set of engines with a greater than usual amount of direct heating surface. Because the firebox still stood between the driving axle and its length and width were no greater than usual, this meant an exceptionally deep firebox.

Class 1953 (Locobase 7035)

Data from the IC 1911 Locomotive Data and 1913ca Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Baldwin was an infrequent supplier to the IC and its American contribution seems to have been limited to this pair. Possessing a bigger boiler than most of the other IC Eight-wheelers, these engines didn't have a comparably sized grate. As a consequence, they probably ran short of steam more readily.

Class 2157 (Locobase 7037)

Data from the IC 1911 Locomotive Data and 1913ca Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

A pair of Americans, about average for the time in the size of their boilers, but possessing small grates, small fireboxes, and relatively modest adhesive weight.

Class 2169 (Locobase 7038)

Data from the IC 1911 Locomotive Data and 1913ca Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Like their Rogers-built stablemates (Locobase 7037), these home-built Americans were among the smallest of that wheel arrangement in service in the mid-1880s. Yet, as late as 1913, they still held places in the IC's roster. One suspects that the low axle-loading had a lot to do with their longevity.

Class 2180 (Locobase 7039)

Data from the IC 1911 Locomotive Data and 1913ca Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

As the IC built its own Americans, it also bought a pair from Pittsburgh. The IC engines' boilers were bigger but the firebox was about the same size and the locomotives generated about the same amount of power.

Class 2184 (Locobase 7040)

Data from the IC 1911 Locomotive Data and 1913ca Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Even for the time, these were small locomotives in every important respect: boiler size, grate and firebox areas, and relatively modest adhesive weight. The latter is perhaps most indicative of the intent of the design. These were light-footed engines that would be welcome on almost any branch line.

Class 2190 (Locobase 7043)

Data from the IC 1911 Locomotive Data and 1913ca Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

These were par-for-the-course IC Eight-wheelers, which meant that they were among the smallest in standard-gauge service in the US at the time.

Class 2196 (Locobase 7042)

Data from the IC 1911 Locomotive Data and 1913ca Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Like the other IC Eight-wheelers of the time, these were among the lightest and smallest Americans in service.

Class 2197 (Locobase 7041)

Data from the IC 1911 Locomotive Data and 1913ca Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Another in a series of small American designs that wound up on the IC. Locobase doesn't know the provenance of this particular loner, but figures it explored branch lines in some of the remoter areas of the IC system.

Class 961 (Locobase 2156)

Data from 1899 Brooks Catalogue.

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 #2716-2723, produced in November 1896.

Boiler was improved Belpaire type. The class was scrapped in 1922-1924.
