Fifth Generation Rail King

Off the Assembly Line and Ready for Sale

Fifth Generation Rail King

 The fifth generation of Stewart & Stevenson’s patented Rail King mobile railcar movers began coming off the Telge Road manufacturing assembly line in November 2010. The G5 Rail King features a Cummins QSB Tier 4i Low Emission engine, a newly designed SAE J1939 CANBUS electrical system, a PLC based mobile controller, a full color LCD display in the cab, and multicolor LED Rocker switch panels. 

Stewart & Stevenson’s G5 Rail King is the first in the industry to have as standard equipment the Tier 4i low emission engine. Fueled by ultra low sulfur diesel, it provides better fuel economy and better performance at lower operating cost. From air filter to exhaust, the Cummins QSB engine is a complete engineered system package with electronic engine management.

G5 Rail King’s newly designed SAE J1939 CANBUS electrical system offers simplified wiring and component installation. It provides seamless high-speed data communication between power train components and enhanced error detection and fault confinement for improved diagnostic capability. It is proven reliable in the harshest off-road industrial environments.

The PLC based mobile controller is programmable for enhanced operator safety and comfort. It has IP 67 Protection Rating, one of the industry’s highest. The full color LCD display in the cab, also with IP 67 Protection Rating, allows operators to view real time engine, transmission and Rail King operating parameters as well as active and stored trouble/diagnostic codes. The multicolor LED Rocker Switch panels are programmable to provide immediate feedback to the operator and change color to acknowledge commands or problem alerts. The panels are vibration, shock and moisture resistant.

As in previous generations of Rail King models, the G5 has independent road and rail wheels for easy mobility on both road and rails. G5’s full-width cab features two independent operator control stations, left and right.

With a wide selection of optional equipment, Stewart & Stevenson can tailor the Rail King to fit individual customer needs. The most popular options are cab air conditioning, centralized lubrication, remote control and cold weather packages.
