Many, many, years ago (around mid-late 90s), my dad and I had a layout. I was still in elementary school, so I dont remember much about it, other than we had mostly Kato and Athern engines, and hundreds of cars, I think mostly Athern. I also know we had DCC. Now everything is in boxes in a storage unit. Recently though, a friend said he wanted to clear out his garage and creat a layout. I told him I have boxes full of train stuff and I would gladly help him out with a layout. I was thinking about it, and I really dont remember much about the actual building of a layout. A few questions I have though are, Has anything changed with DCC? The DCC in all the engines I have is probably 7+ years old, and Im not sure if I still have any of the controllers for it. Would a new controller work with the old boards in the engines? What is the smallest raduis most engines and cars can turn around? What about large engines/cars such as an 89' auto carrier? I somewhat remember Atlas Code 83 nickle-silver track. Is this a good track to use? All of the engines and cars have Kadee couplers, though I cant remember any of the numbers. I was looking at Kadee's website, and it seems they changed (or renamed) their couplers since few still have names like #6 coupler. Will my old couplers work with these newer ones?
