All About Aurora Postage Stamp Trains
4447: Bus Stop Unloading Zone Relay
As far as I've been able to determine, this product was never released by Aurora as a Postage Stamp product, even though it appears in the bus set instruction booklet:
It was manufactured by Faller as #647, which was sold for use in both their AMS HO Scale product line and the N Scale bus system. Note that 4446: Roadway Wire Lead is required to make this work.
