Kansas City Southern / Arkansas & Western 2-8-0 "Consolidation" Type Locomotives

Class 1 / E (Locobase 6825)

Data from KCS 12 - 1908 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

The first locomotive operated by KCS predecessor A & W was this very small Consolidation built by a relatively unknown Massachusetts builder. Locobase suspects that the original date of service came several years earlier.

The profile had a coned boiler with the steam dome just ahead of the cab, a sand dome over the gap between the first and second driving axles and a modestly sized cabbage stack. Note the large percentage of heating surface represented by the long, deep firebox and big grate.

Class E-1 (Locobase 6843)

Data from KCS 12 - 1908 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

These were delivered to the KCS as compounds, but soon converted to simple-expansion engines in 1904-1906 and several were superheated; see Locobase 9446. Those that retained their saturated boilers received new ones with 276 2" tubes and a decrease in total heating surface to 1,974 sq ft. It was this group that was later reconfigured as 0-8-0 yard goats.

Class E-1 - superheated (Locobase 9446)

Data from KCS 12 - 1942ca Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Locobase 6843 notes that these were delivered as compounds, but soon simpled. Some time later, the KCS added superheaters. The usual exchange of tubes for flues - in this case 144 tubes for 26 flues - was the only significant change in the design aside from some weight growth.

Class E-2 (Locobase 6842)

Data from KCS 12 - 1908 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Class E-3 (Locobase 6844)

These were the saturated-steam Consolidations that made up most of the 2-8-0 fleet. Firebox heating surface includes 23 sq ft of arch tubes. They were superheated some time later; see Locobase 5093.

Class E-3 - superheated (Locobase 5093)

Data from home.insightbb.com/~sammy56/folio/fo43-4.jpg (August 2002). Kansas City Southern rebuilt many in this class to three slightly different configurations. The basic data stayed the same, however. Firebox heating surface includes 23 sq ft of arch tubes.

A diagram in the KCS 1942ca Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection notes that Walschaert gear was added to some of the locomotives in 1923.

Class E-4 - superheated (Locobase 826)

Built at Richmond and completed with 24" diameter pistons, 175-lb boiler psi, and low, 57-in drivers. Set originally to 175 psi, boiler pressure soon rose to 185 psi (in 1921) and later to 200 psi when the system was upgraded with thermic syphons.

All but 556, 559, and 560 were rebuilt to the specifications described above. Data from Data from home.insightbb.com/~sammy56/folio/fo43-7.jpg (August 2002).

Firebox heating surface includes 65 sq ft of syphons, 13 sq ft of arch tubes. The addition of syphons meant a 78 sq ft increase in firebox heating surface at the cost of 6 firetubes (not a hard trade-off to accept).

These burly, reliable engines saw out steam on the KCS.
