Railroad/railway fan nudists

My first train trip was from Los Angeles to Chicago on the Santa Fe. I was a 4 yo an when we pulled into Albquerque on the platform local indians were waiting to sell trinkets. They were wearing feathers an war paint. I was so scared as i thought...

I've always been a fan of the forgoten backwaters, the industrial lines, the light railways that sprang up in the uk in the early 20th century, the US shortlines of recent years, & most of all the narrow gauge lines from around the world.
