Purchased GG1 Dec 2016. Just received it back from Lionel for the third time .
It was the pantographs each time .
The response was the pantographs and a cherry switch. They replaced the pantographs anf the board.
The last note I got was a statement that I should watch how I ship it.??? The carton is the same one that I got when I bought it. Still has no gashes or dents.
i guess it's possible that UPS tossed around but it the carton is pristine.
the first time I Sent it they had it 2 months. The second time and 3rd time it was a week.
Took it to a certified dealer the last two times to make sure it was not operator error.
