thanks Richard for your help, I did read some material from Elmer, and it stated the same as you, Need to make sure the Points are working properly, and also, I need to find out what year the Rivarossi is… I bought it on EBay, Not know the company went out of business… I need to have someone put DCC in it and then Run it on Code 83 and Code 100 and see how it runs…It would be nice if everything ran on Code 83…but if not it is Ok for me to have Main lines of Code 100 for the Rivarossi and Run the rest on Code 83… the good thing is I don’t have a Layout yet, so I have time to get this done…Thanks David… and if I can’t I can do what was said from Wazzy, get the Transition tract from Code 100 to Code 83… and make sure all my peco Turnouts are working properly… also, I guess best to get Electrofrogs…
