Waldorf, Md.-based Keller Transportation Inc. added a customized Motor Coach Industries (MCI) J4500 to the part of its fleet dedicated to the high-end business traveler who needs to work comfortably and productively on the road.

Keller’s 50-seat coach is powered by a Cummins ISX clean-diesel engine and an Allison B500 transmission and features all the amenities necessary to create a rolling office, conference and meeting space — Wi-Fi, wood grain-look floors and Bosch AV equipment for in-coach programming. The J4500 includes ten 110-volt back-of-seat outlets for laptops and safety features including an Amerex fire suppression system and a SmartWave tire pressure monitoring system that come standard.

Keller Transportation’s history began in 1927 when Ernest Keller began providing school bus transportation for the Charles County Public School System. The company still operates school transportation, but it began as a coach operator in 1968 and made its first new coach purchase an MCI MC-8 in 1978.

Additionally, Houston-based Continental Bus Lines put its third MCI J4500 coach into service. The company purchased its first J4500 in 2010 and added another in May. Its newest J4500 features an upscale interior and comes equipped with the latest clean-diesel engine technology.

Continental’s newest J4500 features the latest model upgrades including a smooth-handling, wide-ride suspension, electronic stability control, Amerex fire suppression system and the SmartWave tire pressure monitoring system. Added options include three-point passenger seat belts, Wi-Fi and power outlets at every seat.
