Unlike forest fires, you personally can't do much to stop trainwrecks. With that in mind, the folks over at General Electric took a break from tracking your brain on BBQ and devised a way to keep one of the oldest forms of powered-transport on track in adverse weather conditions. You see, the Ardennes Forest in Belgium is legendary for its inhospitable conditions and to sidestep them and the mountains, trains were taking a longer, flatter and more expensive route. That wasn't too economical. So, GE implemented what it calls the Advanced Rail Cleaner for trains on the route. Essentially, the ARC is a module that sits at a precise spot ahead of the front axle and uses high-pressure air (rather than lasers) moving at supersonic speeds to clear away any moisture and debris.
