Union Pacific and Progress
Rail Services said 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.
