Do FlyerChief GP7's and Baldwins work well on postwar AF track, particularly through back-to-back switches? Due to the slight bevel in the base of Gilbert switches there is inevitably some gap in the rails between them. I realize that's not best practice and that you should put a short straight between them whenever possible, but that's not always the case. Some folks have posted that these engines work well on modern track systems like FastTrack and S-Trax that have little to no gaps between sections, but I'm interested to know what they're like on the often less that perfect fitting tracks of our past - present for many, and probably future. Thank you.
PS Not to nitpick the tiny roller design. Actually I'm hoping for good reports of course, but would very much value hearing objectively from those with experience running them on Gilbert track and switches.
