Seeing flames on Chicago’s Metra train tracks isn’t a glitch or a special effect—it’s actually a clever way to keep the city moving in brutal winter weather. Those fires you’ve spotted are real, and they’re lit on purpose to stop snow and ice from freezing up the rails. Without this, trains would get stuck or the tracks could even split apart in the extreme cold! It’s wild to think that fire is what keeps our commutes on track. Would you feel weird riding a train through flames, or is it just another day in Chicago? #Transportation #Chicago #WinterLife
