4-4-6-2
Under the Whyte notation for the classification of steam locomotive wheel arrangements, a 4-4-6-2 is a locomotive with four leading wheels, one set of four driving wheels, one set of six driving wheels, and a two trailing wheels. Other equivalent classifications are: UIC classification: 2BC1 (also known as German classification and Swiss classification) Italian and French classification: 220+031 The equivalent UIC classification is refined to (2′B)C1′ for Mallet locomotives. This wheel arrangement was rare. Two are known to have been built, both as compound Mallet locomotives by Baldwin Locomotive Works in 1909 for the Atchison, Topeka and Santa Fe Railway. They were initially numbered 1300 and 1301 but soon re-numbered 1398 and 1399. These locomotives were perhaps the first and only attempt in North America to adapt the Mallet-compound design for passenger service, and when delivered were the world's largest passenger locos. With a weight of and driving wheels, they exer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whyte Notation
The Whyte notation is a classification method for steam locomotives, and some internal combustion locomotives and electric locomotives, by wheel arrangement. It was devised by Frederick Methvan Whyte, and came into use in the early twentieth century following a December 1900 editorial in ''American Engineer and Railroad Journal''. The notation was adopted and remains in use in North America and the United Kingdom to describe the wheel arrangements of steam locomotives, but for modern locomotives, multiple units and trams it has been supplanted by the UIC system in Europe and by the AAR system (essentially a simplification of the UIC system) in North America. However, geared steam locomotives do not use the notation. They are classified by their model and their number of trucks. Structure of the system Basic form The notation in its basic form counts the number of leading wheels, then the number of driving wheels, and finally the number of trailing wheels, numbers ...

AT&SF 4-4-6-2 Locomotive
The Atchison, Topeka and Santa Fe Railway , often referred to as the Santa Fe or AT&SF, was one of the largest Class 1 railroads in the United States between 1859 and 1996. The Santa Fe was a pioneer in intermodal freight transport; at various times, it operated an airline, the short-lived Santa Fe Skyway, and the Santa Fe Railroad tugboats. Its bus line extended passenger transportation to areas not accessible by rail, and ferryboats on the San Francisco Bay allowed travelers to complete their westward journeys to the Pacific Ocean. The AT&SF was the subject of a popular song, Harry Warren and Johnny Mercer's "On the Atchison, Topeka and the Santa Fe", written for the film ''The Harvey Girls'' (1946). The railroad officially ceased independent operations on December 31, 1996, when it merged with the Burlington Northern Railroad to form the Burlington Northern and Santa Fe Railway.
