I recently got ahold of a 1998 guide to Athearn HO model trains, & looking at the F7's in there, I noticed that sme had a "HiF" rubberband drive. How does this work? I've never knew about model trains having a rubberband drive before. Also, in the same list, I noticed that some were maked "Grd" for geared & some were marked "Pwd" for powered. Is there a difference between those 2? I thought they were the same. Also, what's the difference between a geared F7A & a "super geared" F7A? I know that the F7 I have is marked as a "super", but what makes it different than a normal geared F7A? I noticed that the "HiF" & the "geared" ones were older, like from the '50's & '60's, & the "super geared" ones were made in the '90's.
