Possibly an external whistle control made for a display layout? Looks like 4 rectifier discs and some relays at the bottom. The one device I can see at the bottom looks like a relay controlled fast acting 2 pole switch that would be needed for an external whistle control. Over the years I have come across some odd items made to enhance display operation. Since I never saw an item more than once I assume they were not made by the factory. Maybe a sharp service station tech with time on his hands?

Thank you.  Both devices on the bottom are the same.  I saw no external wiring connection points on this.  It was screwed on to the base.  No other signs of a whistle or such that was mounted.

I was not sure if those were relays or not.  G

Some kind of primitive battery charger for low voltage AC?

I'd bet someone was creating a DC voltage that would blow a whistle/horn when the #132 Auto Stop Station put full power back on a stopped train.

Since it seems clear that it's a home rolled device, you'd probably have to trace out the circuit and see if you could figure out what it was designed to do.

Hi G, you stated above that both devices where the same. That sounds a little like a vibrator circuit. Could it be something that would produce a horn sound, kind of sort of? Or possibly a vibration like the old live stock accessories used?

  It depends on what the source input voltage was. If it was A.C., then the 4 rectifier discs look curiously like a full wave bridge rectifier. If the input was D.C., say batteries, and those items on the bottom are relays, then you could be looking at a very primitive inverter to make low voltage A.C.

  Need a good close-up of the unit, especially the items on the bottom.

Interesting point Larry, if we ask what was the thing doing in the station in the first place then what Gary said about blowing a whistle or horn sounds like a winner.

From the why is it there outlook my vibrator makes little sense. Who would put such a device in the station and for what purpose, to make the people move on the platform?

In any case G could you post better pictures of it from all sides?

If I remember correctly, I beleive it is a ozone depleting Gunkulator. Haven't seen one in years.

Mike Reagan spoke of this in the Legacy tutorial recently. It could also be the type of device the Iranians are using to enrich plutonium.

It looks like someones "rube goldberg circuit" for stopping and starting the train.  Two relays and some rectifiers.  Plus it's on a piece of wood. 

So did I
