Randy, Thanks for the gracious comments and I hope your round house building is as much fun to you all as I had.
I purchased a Marx Airport beacon at a recent train show for a few dollars. It had a dished top beacon bulb and the rotating red and green lens beacon part. I started to look for a place to put it on the layout.
I have an Lionel Airport beacon located on the main board near the round house. I just installed it where it looked good and was out of the way years ago.
Well after a little searching I found out the beacon should be located near the airport as they were used by planes flying at night to help the pilot locate the airport at night. So I decided to locate the new airport beacon near my small Plasticville airport. I also decided the Marx airport beacon tower did not look as nice as an old Lionel airport beacon tower I had in the spare part box so I used the Lionel tower with the bulb and beacon lens from the Marx.
Notice the new to me Lionel 1862 4-4-0 General and tender with the homemade wooden cow catcher and cab I got at the fall TCA train show in Ponchatoula, LA.
