Thanks to all to help with my last problem. New one . If I wanted to bring loco #1 to move up and couple to loco #2 ie two class
20's and then want to move them together and then later on uncouple and move loc #2 away how the heck do you do that with DCC. This is not the same as a dmu unit its the movement of two different locos. Thanks to all who help. Paul
