Jacobs bogie

Common card · No. 419310

Jacobs bogies (named after Wilhelm Jakobs, 1858–1942, a German railway-engineer) are a type of rail-vehicle bogie commonly found on articulated railcars and tramway vehicles. Instead of supporting an individual piece of rolling stock, Jacobs bogies are placed between two carriages. The weight of each carriage is spread across the Jacobs bogie. This arrangement provides the smooth ride of bogie carriages without additional weight and drag. Talgo trains use modified Jacobs bogies that only use two wheels; the wheels are allowed to spin independently of each other, eliminating hunting oscillation.
