Dutch Trains Zap Leaves With Lasers at 5,000°C

When autumn leaves fall on train tracks, they create a slippery film that can delay thousands of commuters and even cause safety issues. The Netherlands found a solution that sounds like science fiction: laser cannons mounted on trains.

Dutch railway company Nederlandse Spoorwegen equipped their DM-90 trains with 2,000-watt lasers that pulse 25,000 times per second. As trains roll along, the beams heat leaves to 5,000 degrees Celsius, instantly vaporizing them into gas.

Each pass cleans a 20-millimeter strip of track. The system runs silently during regular service, turning a maintenance headache into a solved problem.

The technology came from British company LaserThor back in 1999. England's Network Rail tested it but abandoned the project in 2002, deciding it wasn't worth pursuing.

The Netherlands saw potential where Britain saw limitations. After picking up the technology, Dutch engineers refined it and put it into commercial service.

The Ripple Effect

The success in the Netherlands caught attention across the Atlantic. New York's Long Island Rail Road adopted the laser system in 2018, bringing the technology to American commuters who face similar autumn delays.

What started as a rejected British invention became a working solution on two continents. The laser trains now prevent countless delays during fall months, keeping millions of passengers moving on schedule.

Sometimes the best innovations need a second chance. The Dutch proved that persistence and practical problem-solving can turn abandoned ideas into everyday miracles that make life better for commuters everywhere.
