Less Idling. Less Diesel. More Savings with the Banana™ Locomotive APU!

As diesel fuel costs continue to impact railroad operating budgets, reducing unnecessary locomotive idling has become more important than ever. For railroads operating in colder climates, keeping locomotives ready for service during freezing temperatures can mean hours of costly engine idling.

INPS Environmental Products Inc. (IEP) offers a smarter solution: the patented Banana™ Locomotive Auxiliary Power Unit (APU).

Designed to significantly reduce main engine idling, the Banana APU helps maintain locomotive engine temperature and battery charge without continuously running the locomotive’s main diesel engine.
