I agree that would also be a great feature to be able to select complete sections or objects, e.g. completed buildings details and track then copy and paste

This is a good route but I would have made a larger room and put it at the cent of said room that way others could do sections of the Line and thus we could have a larger layout.. but a good job nonetheless.

it is also fun to add a long train going other direction and time it just right at the single track.
