Proto 2000 HO E6 question, minimum radius?

I am considering replacing my Athearn UP F7’s with P2K E6A/B units and am wondering if they will operate on 22" radius. I have not been able to find this spec info. On my new layout, most of my curves will be greater than 22", but there will be some, including the reversing loop that will be 22".

I read at the Life-Like site that they are close coupled with working diaphrams, and am concerned about their minimum radius. I have a set of the new Rivarossi passenger cars with working diaphrams, and they will operate on radius down to 18", though they look terrible doing it. They look OK on 22" though and I would like to used them with E6A/B’s as power.

Anybody out there have P2K E6’s that can help me out?

Ray,

Obviously, the E-series are quite a bit longer than the F-series locomotives. I would have to say that 22" would be an absolute minimum and anything over 24" preferable for both looks and operation. Contact LifeLike and ask them about what their suggested minimum radius is for the E6’s. They been pretty good about getting back to me on previous inquiries.
