So is this why there’s not a ton of sand all over the Tony DeAngelo American professional ice hockey defenseman Carolina Hurricanes T-Shirt moreover I will buy this tracks? It’s only used when necessary unlike how op words it? (Honestly asking) It gets crushed into fine powder by the wheels and then subsequently run over by an entire train. You can see a very thin layer on the rail after application but it’s basically dust so it ends up just dissipating into the ballast or blowing/washing into the surrounding area. Train driver here : yes that’s excatly that. It’s done when needed (can be triggered or interrupted manually too) I feel that it’s important to mention that automotive Anti-lock brakes systems (ABS) do not work by throwing sand down in front of a car’s tires. It’s for uphill traction. It actually reduces efficiency but that’s worth it if means you successfully get up the hill. On commuter rail, the sanding system is like the Anti-lock Brakes system in a car. If you’re in a “spin or slide condition,” the train will sense that and deploy sand to aid in traction. Doing so helps avoid flat spots on wheels that can start forming when the wheels slide rather than turn. This is a problem when those flat spots are hammering into the rail itself and can cause damage from the beating it will give it. Hijacking top comment but: the sanders are used for when we get wheel slip due to wet or snowy rail, they arent used every time we get a train moving. Even going uphill, in warm and dry conditions, sand generally isn’t needed.

Side note, wheels won’t flatten from spinning (wheel slip). Sand also won’t prevent a wheel skid (caused by over braking) since that requires releasing the Tony DeAngelo American professional ice hockey defenseman Carolina Hurricanes T-Shirt moreover I will buy this brakes to achieve. Sand won’t overcome the locomotive brakes. Edit: should have mentioned… sand is used when stopping, to prevent wheel slip in the locomotive brakes, but once the wheel are skidding, it’s too late. Dude thanks for taking the time. Had no clue about the sand. Definitely one of the most interesting facts I’ve learned in a while and I love to learn. The sand isn’t really the most interesting thing… look up dynamic brakes. A modern locomotive is a diesel engine turning a huge generator that makes power for electric motors at each wheel. Because of this, we can basically reverse the polarity in those motors going down the track and use them to slow the train through a process almost like “reverse thrust”. This creates a lot of energy though as your motors are now generators instead. The locomotive has no where to store that energy like a Prius using regenerative braking though… so the energy is routed to a heat grid on the roof and cooked off into the atmosphere as heat. Cool system, and very handy.. but so much wasted energy potential.
