My YMCA Friend's train also include a Lionel #394 Rotary Beacon. Since I have many planes above, I had to find a place for it. The beacon is operated by a finned top over a dimpled bulb. If and when the bulb gets hot enough, the heat rises through the fins, which causes the beacon to rotate. Since this seldom works, I decided to put it near the wall in the winter area by the Helix, and use a lower voltage to power it so it would not light up the wall.
