Abstract: A locomotive suspension system includes a truck frame coupled with a locomotive body frame by one or more upper suspensions and a first motor suspension coupled with a first motor and the truck frame. The first motor is coupled with a first axle of the truck frame. The locomotive suspension system also includes a second motor suspension coupled with a second motor and the truck frame. The second motor is coupled with a second axle of the truck frame. The first and second motor suspensions are asymmetrically arranged on opposite sides of a bisecting plane of a truck wheelbase of the truck frame. The truck wheelbase extends from the first axle to the second axle along a length of the truck frame.
