I thought so, either that, or they were some really ancient ones. The do make excellent clamps, and are impervious to glues, pain, and the like! 
I HAVE STARTED CARVING AND INSTALLING THE FOAM MASONRY. This is slow going but will look really good once the "stones " are painted. I had to darken the photo with graphic converter to try to show some of the cut stone detail.
this is going to take a while
My original plan was to cast the arch detail, but I wasn't satisfied with any of my atempts at making the masters so for now I'm making individual arches, sure they don't meet my full approval, but each one will be ***** up in it's own unique way.

I got Tyler to photograph the process o f cutting some foam stones with my camera at the club last Monday night, and he did a fantastic job. this is what the building is looking like now.

I got almost all the stone work done on the end wall of the tower. Note the saw toot edge on the ends of the wall. this will allow the stones to overlap as I do the other walls. the stones stick out a little farther than they need to, that way, I can trim them down to get a good fit.This final picture looks good. Have seen you do some amazing work. Keep it up.
free materials, and rounding the corner.I don't know if you or anyone else is familiar with the website Shorpy but it's a great site. It has plenty of vintage pictures, most in very high resolution. While I was on there today I saw this and it looks similar to your station Bill: http://www.shorpy.com/node/13894?size=_original#caption Check out the rest of the site and tags under "railroads".
