Charlie, I think Scott told me there were changes between the first series and 2nd. My 1st series 3-rail SAL E7 made a nasty noise going around 072 curves and then one of the universals broke. Scott sent me parts so all is good.
I have since replaced the electronics with BPRC, removed anything that wasn't needed, and it runs fine now, just no sound (yet). Plus I'm now running on 2-rail code 148 track and have much wider curves. The Silver Meteor sure is purty behind that Mint Green E7.
