A long time ago, I'm thinking early '70's I remember an article that was about some Santa Fe street trackage in an industrial area. Just about all the trackage was in the pavement of the streets. The article had a number of pictures, all of them black and white I think. I think it was part of the railroad you can model series they use to frequently run back then. Any one remember this? My MR collection starts about 1971 but I can't find it and am starting to question my sanity!
