Sand anyone?

I have seen numerous prototype photographs showing the sand used by locomotives for traction; around the rails. I am a model railroader, modeling in HO scale. Can you simulate this with…like…say…plaster dust[?]

Hey colin,
Have you ever tried childrens “play” sand fine grade??. I have used that on a couple of dessert dios and it does look good.
Just remember to add tones of brown, tan and other earth tones to help aid in the weathering factor.
Flaps up, Mike
