To Chrissaf, At the age of 67 and not had a train set for 56 years you've totally lost me in your confusing paragraphs! with firmware, versions, upgrade etc.Your assuming I understand about everything thats been produced in DCC. I understood on advice that DCC was easy? As the last controller I had was 56 years ago, it went forward and reverse and I have not run a train since. It seems that simply having a new DCC controller and engine is not enough. You've confused me for asking what I thought was a straitforward question. I can understand why people argue about staying with analogue. Totally lost the plot, regards Graham
