Wa -a-a-a-! I wonder if the trailing truck from the Old Rivarossi / Con Cor version if these locos would be any good? The locos are found fairly cheaply at Swaparamas ,check Con Cor's spair parts dept. to see if they even have this part. Just a suggestion. Sorry I don't have any of these engines any more, or I would let one go for a parts source. I replaced em with two of the now Walthers then Life Like locos a C&O and an NKP. Nate Goodman (Nato).
