Originally built by Great Northern with relatively tall drivers for a compound articulated. They presented an imposing appearance, showing a high Belpaire boiler over ten axles of running gear. Firebox heating surface included 81 sq ft (7.53 sq m) of combustion chamber All four cylinders were fed through 15" (381 mm) piston valves.

Under the Whyte notation for the classification of steam locomotives, 2-8-0 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles, and no trailing wheels.

In the Whyte notation for the classification of steam locomotives by wheel arrangement, a 2-8-8-0 is a locomotive with a two-wheel leading truck, two sets of eight driving wheels, and no trailing truck.

These long-stroke, Belpaire-boilered Consolidations continued the line of such 2-8-0s that began with the Rogers F-5 engines (Locobase 8825). Within a decade, the GN superheated the first of ten F-6. All 25 engines left the roster in 1926-1927.

The mountain-shrinking 2-8-8-2 was the all-time giant of Great Northern's steam fleet -- and the largest locomotive in the world when Baldwin built the first of its class. Most of the big R's, however, came from the railway's own shops at Hillyard, Washington, and were the first steam locomotives built in the Pacific Northwest.

The first 2-8-0 was built by Matthias Baldwin in 1866. The locomotive was named "Consolidation" in honor of the recent consolidation of the Beaver Meadow, Penn Haven & White Haven and Lehigh & Mahanoy railroads into the Lehigh Valley. The Consolidation became the principal hauler on most main lines.

The Great Northern F-8 is a class of 125 2-8-0 "Consolidation" type steam locomotives built by the Rogers Locomotive and Machine Works, their corporate successor the American Locomotive Company, and Baldwin Locomotive Works between 1901 and 1907 and operated by the Great Northern Railway until the mid 1950s. They operated throughout the Great ...

Feb 27, 2025 · The GN continued to refine their fleet of Consolidation Mallets, overhauling the units in 1940 with, among other improvements, roller bearings and a boiler rating of 265 psi. The more powerful 2-8-8-0s were used in both passenger …

CLASS 0 • MIKADO. The popular Mikado (2-8-2)was best exemplified on Great Northern by the celebrated 0-8.The first three engines in this sub-class(3397-3399) were GN-builtin 1932, and were the only locomotives constructed in the U. S. that year for domestic service. The 0-8 was not only the heaviest Mikado type ever

Working: 265 psi.
