Hi Andy, hope you are having an awesome day. I wanted to reach out because, I seen you are a European with a 12v track train in the US. If this topic has already passed, and you had given an answer, I am truly sorry for having to reiterate. This weekend I started building my 12v trains for my son, but when I boxed everything in Europe/The Netherlandsd and shipped over here, I for some reason never thought about the voltage swap from 220 to 110. May I ask how you are able to operate your 12v train in the US and what I will need to run it (maybe with links to your hardware)? I am a numbers/accounting guy, never new much about electricity. I left the transformer (https://www.worthpoint.com/worthopedia/siemens-hema-ho-transformer-power-411311477) in Europe thinking they had something similar here, maybe you are able to help me and my son on our way so we can operate this awesome track? What did you use for a power converter and the transformer with the speed dial to operate the train? Thanks in advance, and I hope you have a great day.
