David Wardale
The 5AT Advanced Technology steam locomotive was a conceptual design conceived by the British engineer David Wardale, and first described in his definitive work on modern steam, ''The Red Devil and Other Tales from the Age of Steam.'' Wardale's purpose in putting forward the "Super Class 5 4-6-0" design concept (as he then called it) was to offer a future for steam hauled trains on the main lines in the UK on which the use of heritage traction is likely to be gradually phased out as the speed and density of commercial rail traffic increase. Work on the project was suspended in March 2012 following completion of a project Feasibility Study and subsequent failure to raise the finance needed to complete the detail design and construction of the locomotive. Proposal Wardale's proposal was for a locomotive that would: * be acceptable to the British railway authorities by conforming with the size and weight of the BR Standard Class 5, BR 5MT Class 4-6-0 locomotives that have operated o ...

4-6-0
A 4-6-0 steam locomotive, under the Whyte notation for the classification of steam locomotives by wheel arrangement, has four leading wheels on two axles in a leading bogie and six powered and coupled driving wheels on three axles with the absence of trailing wheels. In the mid-19th century, this wheel arrangement became the second-most-popular configuration for new steam locomotives in the United States, where this type is commonly referred to as a ten-wheeler.White, John H., Jr. (1968). ''A history of the American locomotive; its development: 1830-1880''. New York, NY: Dover Publications. p. 57. As locomotives pulling trains of lightweight all-wood passenger cars from the 1890 to the 1920s, they were exceptionally stable at near speeds on the New York Central's New York-to-Chicago Water Level Route and on the Reading Railroad's line from Camden to Atlantic City, New Jersey.
