There's not much, the book
I LIVED IN THE RICO DEPOT has a little bit of description of the interior of that depot. I think there might be a blurry photo or two of some of the interior as well, but it's not much (and in my copy, the photo reproduction was pretty poor).
But - it's a great book in any case. Tells a lot about living in Rico in the 1950s. There's only a chapter of two written when the RGS was still operating; the rest of the book is about the years afterward.
I've got links for that book (as usual for all RGS books!) on my site: [
