Wow, this is a pretty international group, just like the Ford Model T Club of America I have a 'vintage' Marklin Z layout - fully 'old school' analogue, which I am seeking to refresh and a larger DCC N scale layout, largely Arnold, that is due for a refresh (aka major rebuild). I look forward to advice and guidance as I learn my way through 21st century DCC and 'Arduino' technology for that project. Adrian Whiteman Canterbury New Zealand
