Im not sure if this is the right forum to post this but i have a question about transformers. I have the polar express R2R set and am on my sencond transformer. the first one stop working all together. i only set up this set around the holidays when i went to set up this set this year the transformer is making a weird humming noise that it didnt make last year. is there anyway to get this serviced or should i buy a new transformer? If i go the route of buying a new transformer what one should i get? currently i am just running around a simple boring oval. i have no switches or accessories hooked up to my layout, but next year i am thinking of adding switches and some elevated sections.
