A mechanical linkage connecting the suspension springs of adjacent axles on a locomotive truck or bogie. It acts as a lever to transfer load from an axle that dips into a track depression to the adjacent axles, keeping all wheels firmly planted on the rail. This continuous weight distribution prevents derailments on uneven track and maximizes traction.
