Testing out some Bachmann EZ track with the most temperamental train I have, the Varney Aerotrain. Cobbled together from a dummy set, this intriguing vintage piece won't stay on the track if you stapled it. The coupling and wheels have been removed, reset, realigned, with marginal results; any small defect and it eats ties. No more trouble now!
I have some memory of hearing that tune before. But, can't remember where or when. Back in more active days I think.
