Nuthin wrong widdat...My HO layout is 4 loops of track on just over 17 square feet---not quite enough room for 65 engines and 250+ cars.
I used to do all the dolled up weathering, kitbashing and fine details---still do---but I've found great pleasure right now in just picking/cleaning/fixing/tweaking the old stuff. Even now I'm hunting for the third coach and locomotive for TYCO's Hooterville Cannonball from the old 60s TV show "Pettycoat Junction...picked these two up for peanuts in a forgotten junk box at a local open house...
...How 'bout a 7-11 promo car...?
...or a REALLY BLUE
Western Union car...?
...or a dual motored TYCO F9?
These are the pieces that carried the hobby into the mainstream that are now being tossed aside for the highly detailed, limited run stuff from Atlas, Kato and BLI. Their stuff is nice enough but, quite frankly, even if I could afford $35 boxcars, I don't know that I'd really want to.
These pieces are hardly worth much but they were the stuff of dreams when I was growing up and will always have a home every time a $20 box load of them comes my way.
