Proviso Control Tower

   Today I finally started work on the Proviso control tower.  As you can see from the photos below, the prototype is a very unusual looking tower.  More reminiscent of an airport tower or, according to my wife, a prison tower.

   Thanks to David K. Smith, I had drawings that I could use to build a mock up.  After having the mock up on the layout for a couple of months, I determined that building the structure full size would make it too big for my scaled down version of the Proviso yard.  For one thing, the prototype has two stories which makes sense for a very large yard complex with three yards; hump, inter-modal and flat.  But, it is overkill for my scaled down version which only has one yard.    The other thing is that the full size height simply overpowered the rest of the structures, which are all scaled down versions of the real thing.  So I reduced the size to 85% and removed the second story.
   I printed out the reduced drawings, taped it to Evergreen .030" V-groove styrene, cut out the four sides and glued them together.  Since the windows go completely around the tower, the windows were cut off completely making the roof section separate from the rest of the structure.  I also added a floor.

   To connect the roof section to the base, I glued four .030"X.030" styrene strips to the base.  I then glued the roof section to the four posts.

   Next, I used more .030"X.030" strips to represent the remaining posts and to strengthen to connection.  Lastly, I added four small horizontal pieces to complete the windows according to the prototype.

Here's a comparison with the full size mock up.

   At this point, I need to paint the structure, put in an interior and add window glazing.  Stay tuned!


  1. Looks very nice!

    Selective compression applies not just to what we choose to model but also to how we model our structures. I think you've pretty much nailed it.

  2. Thanks Collin. One area I'm concerned about is getting tinted glass for the windows.
