Hello,
I have a Lionel Type VW transformer that I’m using with the Polar Express Train set. When I activate the whistle switch the whistle doesn’t sound. It seems like there’s a voltage spike when I activate it because the train speed increases. Could it be that the diode is bad in the transformer even though it speeds up when activated? I know the whistle in the engine works because it sounds with the transformer that came with the set.
