The Diesel Commuter Locomotive -- Raising the Bar on Performance and Noise Abatement

In 2005, faced with a strong growth in ridership and the need to operate heavier train loads, NJ Transit introduced the most powerful four-axle diesel-electric commuter locomotive in North America. With a gross rating of 4200 HP, all thirty-three of the units were completed by Alstom Transportation at its Hornell NY, plant in 2004 and are actively undergoing commissioning trials before full entry into service. Built in full compliance with the Passenger Equipment Safety Standards under 49CFR238 and the EPA Tier I emissions requirements under 40CFR92, NJ Transit also called for the equipment to meet stringent levels of performance and noise abatement. In addition, with a challenging weight limit of 288,000 lbs for operation up to 100 mph, the specification raised the bar on the designers to develop a locomotive for the twenty-first century. This paper describes the features of the PL42-AC locomotive in detail with particular focus on the way in which it meets the high-performance and noise abatement criteria.
