Hello
I am French and I make my debut in the digital
I would buy EZ Command ® Dynamis scale train ® Infrared Wireless System DCC and N, eg
  DCC-Equipped Steam Locomotives "Spectrum Canadian National # 4201" can it work without adding anything else.
Should we add a rail or a specific power cable?
Should keep my Transformer FLEISCHMANN 6755 or not?
The analogue train will they still work on the same voice
As I said I would started in digital and my English is not good
Thank you in advance
