I was into HO when I was growing up. Grandfather is gone now and this past Christmas I wanted to run the Lionel stuff he left for the family. Opening the storage container the items were wrapped in newspaper from 1994 which would be my guess the last time the equipment was used. I dusted it off and did the quick once over and it fired right up no problem. Ran perfect for the whole season. Now the locomotive is in for a cleaning, tune up, once over at the local hobby store. First time its been in for service (that I know of) in 35 years. So the Lionel bug has bitten and since early December I've been picking up post war Lionel when I can. I'll never pack granddads train away again, only in a display case I'm building. So... way off track here (no pun intended). I picked up a ZW 250w transformer for more then I should have but oh well. It seems fine, but wondered if it should have a constant hum when its plugged in? I know its significant more powerful then my 1033 transformers so wonder if its normal operation? *****************************************************
