Last crawled date: 2 years, 11 months ago

Freely inspired by the Mountain Class locomotives (4-8-2); Full interior cab with quadrants, indicators and train controls. 4-8-4 represents the wheel arrangement of four leading wheels on two axles, usually in a leading truck, eight powered and coupled driving wheels on four axles, and four trailing wheels on two axles, usually in a trailing truck. The type was first used by the Northern Pacific Railway and is consequently most commonly known as a Northern.The 4-8-4 wheel arrangement was an obvious progression from the 4-8-2 Mountain type and, like the 2-8-4 Berkshire and 4-6-4 Hudson types, an example of the 'Super Power' concept in steam locomotive design that made use of the larger firebox that could be supported by the four-wheel trailing truck, which allowed improved free steaming, particularly at speed. This was combined with the stability at speed brought about by the four-wheel leading truck and the greater adhesion of the eight-coupled driving wheels. #482 #484 #Class #Locomotive #Mountain #Railroad #Steam #Train
