After ~20 years I've finished my layout. I have plenty to do as I am always building more cars, engines, trolleys, structures, etc. There is also 1 fairly large lift out at the one end that I have 2 blanks already in hand with the track already installed. I figure I have a 2-5 years to complete each of these with structures and scenery such that I can rotate these 3 completed lift outs into place.
Maybe I'll move up to F scale next!
