Reorganization:
Since I like running my vintage old cars I moved all my vintage metal Athearn, Varney and wood Silver Streak, Ambroid cars that were in the St. Paul yard to the Seattle freight yard.
The vintage cars takes up about 3.5 tracks.
One 'string' is on the 'road' but there are about 130 vintage cars available for trains.
The St Paul freight yard gets all the 70's and 80's (also my age bracket!) Athearn, Train Miniature, etc cars.
Don't remember who made this but it weighs a ton.
Something different: aluminum foil covered.
Some exceptions:
Have several contemporary made cars that are really nicely detailed.
...and any 'gons' or 'flats' with loads.
...and last, the TM 'state of Maine' potato cars. Remember back in the 70's when these came out, I had to go to every hobby shop in Cleveland to get a nice string of them as each hobby shop only had one or two of them.
The Athearn, etc cars of the 70's/80's also have some nice graphics.
