I've been wanting to build a rail setup in my yard for a while but I'm not sure how or what materials to use, especially for the ramp. I only have about 22-23 feet of room. A price range would also be helpful.
I made my setup out of a wooden ramp layered with fencing and a patch of turf at the end before the rail which was a PVC pipe screwed onto wood elevated at the front so it would be flat on a down hill. Honestly my best tip would be is to scavenge any plastic or wood around your house, make somthing simple and then upgrade it over time. It will be cheap and the constant upgrading makes things interesting.
