You are so right. I love to see beautiful engines, upgrades and layouts. Because I am Hi-rail, I don't envy Scale nor look down on old unmodified Flyer, it's all good. When I retire, I have a list of projects to do and complete: the update of the K5 as above, completing my 2 Reading T1 tenders and converting my 290 Reading into a G1 or G3 Pacific.
I love the work you did making scale passenger cars out of old flyer. I have that article from the net to kit-bash the cars to Reading. I guess if I find cars cheap enough, I will do some. If not, American Models makes undecorated 4 wheel truck passenger cars. My problems with them are, they have the wrong roofs and the couplers drag and decouple. I devised a method of preventing the droup, take a piece of brass rod, bend it like a C, then drill holes near the edge and glue one on each end. The beauty of this is, it shouldn't restrict coupler travel.
I haven't found that drive axle for the 322 AC, I thought for sure someone in the club would have one, but Allentown's coming up and NPS is there displaying. As a matter of fact, I already have committed to spending over $100 for the upgrade to the 322 (electronics). Nothing happens quick when you don't have alot of money.
