Bill Wade has described some of the differences, but most people think
AF was only the 19" radii--don't forget AF PikeMaster track that was 15"
radii. AF had to modify both their GP-7 and the PA's. I don't think
the Northern would run on the stuff and I can testify that my Hudson
didn't like it.
My thoughts would be to check with the engineer who might have been
working on the SHS's E-7 model. If they had engineering drawings,
Lionel could arrange to steal them. Woop's isn't that's what happened
some years back?

An important difference between A F and Lionel O-27 is A F has broader
curves. There is no need to go to such extremes of swinging diesel
pilots and dual motors for compensation of very sharp turns. I am sure
>many< SHS locos spend their time running just fine on A F track with
fixed pilots etc.
If only this info could get to the correct designers for future items.
What works and is necessary for O-27 does not apply to S even for Hi
Rail use.
Thank You,
