Kudos #2, Dave. I have seen something like the P:87 loop you mentioned in a video on some web site. Some guy took a very tight radius oval on a hand-held board with two or three P:87 wheel equipped cars on it, held the board in his hands and moved the board around so that the cars rolled around the track. NEVER ONCE did they derail... and they got up to a fairly high speed at least a few times.
As for the reliability of P:64 wheels... surely there will be some 'forgiveness' when they are used in sprung trucks (as opposed to rigid trucks). Comparing freight trucks to locomotive trucks... once can almost expect to have more trouble from the loco than the sprung freight truck since the axles on the loco do not has as much (if any) freedom for the axles to 'twist' in the assembly... which can lead to varying amounts of down force on each wheel on less than perfect track. Naturally, when one wheel 'gets light', it will have more tendency to ride up on the rail. So very good to excellent track is almost a necessity for P:64. But who (in their right mind) would WANT anything less even when using all code 110 wheels?!? Easy is cheesy, great is worth the wait (and effort)... which explains why 1:1 railroads used 1" diameter grabs/railings when something smaller would surely have worked.

Hi Bill, Then that would limit S scale modelers to about a 17 inch minimum radius if they wanted to model something like the Harlem Transfer which used 90 foot radius loop around the freight house :>) . BTW I built a 90 foot HO test loop and found P87 stuff had no problem going around it even using some 50 foot cars so I have good reason to believe that P64 would work pretty reliably on something like 30 inch radius if someone was considering it....DaveBranum ------------------------------------ Yahoo!
