Union Pacific and Progress Rail Services Ultra-Clean Diesel Locomotive for Intermediate Line Haul Service Achieves 500 Service Hours Milestone
OMAHA, Neb. — Union Pacific Railroad and Progress Rail Services announced that the ultra-clean diesel PR30C-LoNOx locomotive being tested in intermediate line haul service has successfully achieved more than 500 operational hours. The locomotive — powered by a 3516 Caterpillar engine — has been retrofitted with a state-of-the-art after-treatment system, making it one of the cleanest locomotives operating in the United States. The prototype intermediate line haul locomotive has more power than the typical 2000-horsepower 4-axle Genset “switching” locomotive used around terminals, but is less powerful than the 4400-horsepower 6-axle “line haul” locomotives used for transcontinental freight service.
