Why Does a Locomotive Pour Sand on the Rails — and Why Might the Train Not Move Without It

Why does a locomotive spread sand on the tracks when it has so much power under the hood? In this video, we’ll break down how the wheel-rail interaction works, why a locomotive starts to spin its wheels, and how ordinary sand helps transfer traction to the tracks and get a heavy train moving. You’ll learn how a locomotive’s sanding system works, what happens when the wheels spin, and why even thousands of kilowatts can be useless without sufficient traction.
