A North Knoxville company has come up with an innovative way to update aging trains by making them quieter, more fuel efficient, and less polluting.

Locomotives have to be rebuilt every 10 or 15 years.

New standards require them to be much less polluting but replacing the entire system is expensive.

Now Knoxville Locomotive Works has patented a repower system that replaces the motor but keeps some of the original equipment.

The call it the KLW20B.

"We've produced a locomotive that is much, much cleaner than the original one, 30% more fuel efficient, and much cheaper to rebuild and achieve all those goals than any other option that's out there right now," Knoxville Locomotive Works President Doc Claussen said.

A locomotive with the repower system is new so it looks a lot cleaner. But it's also a lot quieter and sounds more like a truck than a train.

Knoxville Locomotive Works estimates more than 10,000 locomotives will need to be rebuilt over the next decade.
