NTS&B Hidden Military Base Bunker Door Started

The last module I had to build was the bunker door assembly.  It sits on the end of the hidden track at the Top Secret Headquarters, where the Lionel #44 Army Missile Launcher lies waiting for action.  The assembly will consist of 1) a 'dummy' track bumper mounted on the door to simulate the end of the siding just past the coal loader, 2) an operational door for the bunker, 3) Track power for the bumper and siding, and 4) Power for the Lionel Radar tower which will sit on top of the bunker.   Here are the initial pictures:

I used a slow speed DC motor I had purchased a few years ago for this project.  I used fishing line to open the door, and added counter weights under the bumper to help close the door.  Limit switches are hot glued on to the side of the frame, and on the motor casing.
