Problem-free Operation

Operator safety and comfort is enhanced through the programmable PLC Based Mobile Controller. The Rail King® cabís full-color LCD display allows operators to view real time engine, transmission and operating parameters, and active and stored trouble/ diagnostic codes.


Quick and Easy Repair

Smooth high-speed data communication within power train components, enhanced error detection and a fault confinement system delivers improved diagnostic capability.


Sturdy Mechanisms

Couplers made of fabricated steel create huge shock absorbing isolators. These were manufactured and patented by Stewart & Stevenson. The modern weight-transfer system instinctively enhances tractive effort for improved pulling power.


Low Emission

Fueled by ultra-low sulfur diesel, these Rail King models offer better fuel economy and better performance, at low operating cost.
