On August 27, 2002, the DMU began testing at the Transportation Technology Center in Pueblo, Colorado. The regimen included over 1,000 miles of shakedown runs, several laps at 90 mph, sprints up to 110 mph and a full battery of rigorous testing. The DMU met or exceeded test benchmarks for acceleration, braking, HVAC, and wayside/interior sound levels. Also the DMU exceeded fuel efficiency expectations dramatically by achieving two miles per gallon.

"It's great to see an American manufacturer step up and develop
a DMU that meets the FRA and APTA standards," commented Bill Millar, president of APTA, who attended the testing.
