I have vague memories of a train set from the 70's. The compartments opened up to reveal an kind of secret agent HQ-I don't recall it being part of a line/franchise. I am also sure there was a "baddies" set with a mountain scenerio-Can anyone help me. I definatly saw this in cataloques/shop windows in England in the mid to late 70's, but it wasn't widespread.

I remember that, fucking quality it was!!
