They are disappearing - at least around by us - the old train tracks have been converted to bike & hiking trails. My husband & I ride our bikes on them several times a week during good weather (when it's warm enough).
This is not a real train track but a miniature model. One train hobbiest has builds large size trains that people can actually sit on top of. Once a year, he opens his yard to the public and people bring their kids and they hop on one (of several) of the trains he has made. He doesn't charge but does ask for a donation. Kids love it, many adults do too. He has very unique, and even antique trains as well. His trains come in different sizes.
