“The laser train prevents all of this and covers hundreds of miles every day without getting in the way of regular train service,” the voiceover says in the social media video. “Thanks to the laser train, Metro-North has seen a 30% reduction in wheel defects and a 65% reduction in train delays caused by leaves.”

SEPTA’s secret weapon against slippery fall leaves? Overnight wash trains. But as NBC10’s Andrew Rowan reports high-tech solution could be on the horizon.

The Massachusetts Bay Transportation Authority (MBTA) and Keolis are tackling the challenges of slippery rail season in Southern New England with a new laser train. The train uses laser technology to blast a greasy substance from leaves off the tracks.

"We’re able to use the laser train even past freezing conditions when we have to actually sit the waterworld down,” Scholes said. “Therefore, we're able to operate it over greater environmental conditions and we're able to cover a lot more ground with it and do the entire network in a single day, whereas with waterworld, we're only operating at about 12 mph."

Metro-North was selected as a Gold Award winner for Rail Safety for its use of laser technology to remove residue caused by crushed leaves.
