I found on YouTube last night a very old video that was posted by The Baltimore Sun Newspaper. The video is of a Christmas Train Garden that was in a Baltimore City Fire Station(which one I have no idea). The video is posted as being from the 50's/60's and it is in B/W. The first part of the video is boring with just a punch of shots of firefighters in the station until the 4:40 minute mark which goes into them starting to build the display. I believe it is from the late 50's from some of the Lionel trains that they are using like a Wabash GP-7 & B&M GP-9 and one loop of super 'O' track.
The question I have is who made the electric monorail system that they have in the display? Later on in the video it shows them still in the construction of the display and a FF is trying to get it started and removes 2 of the units and then pushes the motor piece with a stick. And then they show someone trying to put a couple of pieces of the track to the monorail together.
