Variable-load air-suspension arrangement applied to intermediate truck of B-2-B diesel-hydraulic 2000 hp DD51 locomotives makes it possible to obtain consistent adhesive weight for traction and provide flexibility of operation by transferring weight from driving axles to carrying axles, when running on lighter track; axle loading on traction trucks can be reduced from 15 ton to 14 ton by increasing axle load of intermediate carrying truck; however, driving axle load is increased automatically to compensate for loss of weight on driving axles as service supplies are consumed on board locomotive.
