Chicago & Eastern Illinois 4-4-0 "American" Type Locomotives

Class 100 / 475 (Locobase 7146)

Data from the C&EI 11 - 1911 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

These two little Eight-wheelers were delivered 4 years apart.

Class 101 / 476 (Locobase 7147)

Data from the C&EI 11 - 1911 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Class 103 / 207 (Locobase 7138)

Data from the C&EI 6 - 1904 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Locobase described the C & EI's Pittsburgh engines of the same year (Locobase 7126) as small, but this Baldwin was positively toy-like.

Class 104 / 59 (Locobase 7126)

Data from the C&EI 6 - 1904 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Even for its time, this was a small Eight-wheeler design in all respects from cylinder volume to firebox heating surface to adhesion weight. Its profile was typical: deep, narrow firebox dropped between the driving axles; steam dome over the firebox and just ahead of the cab; long first boiler course with sand dome, and straight stack.

Class 106 / 471 (Locobase 7148)

Data from the C&EI 11 - 1911 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

This was a freight Eight-wheeler.

Class 107 / 490 (Locobase 7149)

Data from the C&EI 11 - 1911 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Class 108 / 491 (Locobase 7150)

Data from the C&EI 11 - 1911 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Class 111 / 201 (Locobase 7137)

Data from the C&EI 6 - 1904 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Locobase doesn't know the provenance of these locomotives, but they seem to have been bought as freight engines. The C&EI 10 -1912 Locomotive Data book says that they were originally all alike. Then come the details that show how one class could fragment over time: "201 has tires increased to 68" OD. 202 has tires increased 62" OD and cyls bushed to 16" x 24" . 203 has cyls bushed to 16" x 24", thus giving all a different tractive power."

Class 115 / 494 (Locobase 7151)

Data from the C&EI 11 - 1911 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Class 117 (Locobase 7152)

Data from the C&EI 11 - 1911 Locomotive Diagram book book supplied in May 2005 by Allen Stanley from his extensive collection.

Class 121 / 98 (Locobase 7128)

Data from the C&EI 6 - 1904 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

These were middle-of-the-pack Eight-wheelers compared to their contemporaries on other US railroads. Like their Pittsburgh predecessors (Locobase 7126), they had deep, narrow fireboxes between the driving axles, steam dome over the firebox, long narrow first course to the boiler and a straight stack. Heating surface and cylinder volume had grown some and the drivers were taller.

Class 125 / 96 (Locobase 7127)

Data from the C&EI 6 - 1904 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Compared to the earlier C & EI Eight-wheelers, this quartet had an unusual profile. Gone was the great swell over the firebox; instead the barrel ran straight from backhead to smokebox. The firebox still sat between the driving axles, but the steam dome now was located ahead of the lead set of drivers, close to the sand dome. Otherwise, the design was little changed in size from the earlier Schenectady engines (Locobase 7128).

Class 150 (Locobase 7132)

Data from the C&EI 6 - 1904 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

This locomotive resembled the 96 class (Locobase 7127) in its straight barrel and position of the steam dome forward of the firebox. But the firebox had changed shape considerably and now rested over the driving axles. This had the effect of shortening the boiler tubes, which reduced heating surface while expanding both grate area and firebox heating surface.
