I measured my Atlas and Lionel GP9s to see what the difference was.
The Atlas measured 2.21" over the bearing caps, the Lionel measured 2.26", .050" difference. That doesn't sound like much but looking at it, it appears to be much more.
I wish they could be perfect for every model for every RR that owned them, but they can't. I guess it's up to us to dig out the tools and modify to get what we want. It's funny that I don't mind cutting into a $600 engine, but I don't buy them to resell, I buy them to enjoy
I may take the fuel tank off the E7 to see if that's where the noise is coming from, maybe the drive shafts are rubbing.
