I recently purchased a Lionel steam engine on eBay. It was from the 2018 catalog. I purchased the train at a low price and thought I got a good deal. The seller had 16 of the same engine for sale. He had sold 13 of them so I bought the 14 one out of the 16 he was selling. I opened it up and it came in a brown Lionel box so thought it was authentic. When I took the remote out it had something broken inside the remote. I put the train on the track and turned on the power and get a really high pitch electric humming. It connected to WiFi and the train worked but with a high pitch sound especially when I hit crew talk. Is it possible that this was a return on a bad sound board and when Lionel gets a bunch of the same product return they sell these to distributors or anybody who wants to buy the same lot. Something was fishy with this right out of the box. The train I bought for 240 bucks is
Lionel Union Pacific LionChief Plus A5 #218 6-84968 O Scale Transformer Control
Thanks for responses.
