When grades get to steep for real trains they have the ability to drop sand in front of the wheels to gain some more grip and help overcome the grade. I have a grade that is a bit over 2% in my layout. If I want a layout in my house I have no choice but to live with this limitation. I thought once a saw a product that helped slipping while going up steep grades. Does anyone now of such a product, a google search did not rewveal what I was looking fore. Anyone know of such a product?
