Anyone have any info on Model 9 transformer. I found it in the garbage about 10 years ago. It is a 150watt single control transformer. Not a 9B. 5 terminals. 6-14 v, 14-22 v, 22-30 v, 7 v, 14 v and whistle control hook up. The transformer works. It has a jewel lens light and a circuit breaker. I can't find anythimg on the net. Not sure why they would produce a transformer with up to 30 volts unless it wasn't for running trains
