I have a friend who has a bunch of Marklin Trains from when he was young, but no transformer. Both Lionel and Marklin are 3 rail AC. Could a Lionel transformer be used with out harm to the Marklin Locomotives ? His trains are from the 50 - 60s, not the modern stuff.
I was thinking something like a Lionel 1033 or 1034
Anybody out there have knowledge about Marklin to answer this question.
