Album Info:
The 4-8-4 was an obvious progression from the 4-8-2 "Mountain" and, like the 2-8-4 "Berkshire" and 4-6-4 "Hudson" types, an example of the "Super Power" concept in steam locomotive design. It combined the stability at speed of the 4-6-4 and 4-8-2 due to the 4-wheel lead truck, the greater adhesive weight of the 2-8-4 and 4-8-2 (leading to greater traction, and allowing a larger, more powerful locomotive) and the larger firebox supported by the 4-wheel trailing truck common to 2-8-4s and 4-6-4s (allowing for freer steaming, particularly at speed).
