Welcome to the site.I have a Lionel whistle tender with a Lionel 60 watt 1041 transformer. The tender will whistle when powered up alone but when I put a locomotive on and pull it around the track it will not whistle. If someone could help me it would be much appreciated.
i have 3 of them that all do different things... at first none worked..Thanks I will try cleaning the commutator and checking the brushes. Thanks for your input!
