Thanks for your response.....I don't think this is a new version. This appears to be new old stock. I paid $25.00.

Bought a Bachmann trolley at the Novi Michgan train show today. I was told by the booth owner that it was new and he tested it. It runs pretty good but has a pretty loud "clicking" noise. I think this is common with thses but I am wondering if someone knows what the fix is? Thanks.
