Volvo Penta, a manufacturer of engines and complete power systems, has been selected to power the new Rail King RK460, a mobile railcar mover that was introduced this year to the North American market by Houston, Tex.-based Stewart & Stevenson, an authorized Power Center and Distributor for Volvo Penta.

Railcar movers are highly specialized, heavy-duty vehicles used to move small numbers of cars off-track around railroad yards. Weighing more than 45 tons and powered by the six-cylinder inline turbocharged Volvo Penta D8 Tier 4 Final diesel engine rated at 320 Hp, the RK460 is being hailed as the world’s largest steel mobile railcar mover.

The EPA Tier 4 Final engine uses Volvo Penta’s fully integrated SCR-based exhaust aftertreatment system that eliminates the need for a Diesel Particulate Filter (DPF), “maximizing uptime and minimizing emissions on the job,” says Volvo Penta.

“We selected the Volvo Penta D8 Tier 4 Final engine for the Rail King RK460 because of the power output, unmatched torque output at low RPMs and reduced fuel consumption, noise, and vibration,” said Rail King Product Line Manager James Lyon.

“The new railcar application is a natural progression in the outstanding working relationship between Volvo Penta and Stewart & Stevenson,” said Darren Tasker, Vice President of Industrial Sales at Volvo Penta North America. “We are looking forward to Rail King operators experiencing the quality and efficiency of Volvo Penta products and building further on that excellent foundation for other new projects.”
