Running Lionel PE Trolley on Superstreets?

If you are talking about this PE trolley (below), it cannot be modified as I spoke about because it does not have swiveling trucks.  These two-axle trolleys have fixed axles that do not swivel.  My experience is that they negotiate D-21 curves well enough, slowly noticeably but acceptable, but tend to really slow on D-16 curves.  

Thanks for the quick reply Lee!  That's the model I was looking at and I hadn't even considered whether it actually had swiveling trucks or not.  From a longevity standpoint have you noticed (or do you have any opinion as to) whether one of these slowing down through the tighter curves contributes to additional wear and tear on the motor?  I'd hate to burn the trolley out just to run it on superstreets instead of regular track.  

Probably won't answer your question, but I've been running a Lionel Fort Collins trolley (similar, if not exactly the same as the PE one) on a public Christmas display layout for the past 5 or so years.  The first couple years it was on a simple O-27 loop, but it's been running on a fastrack O-36 loop the past couple years.  The pickup slider is about the only thing that's shown much wear, although the axle holes may be enlarging too.  As long as the track is clean it runs fairly well.  If the PE ones weren't as expensive as they are, I might consider picking one up to replace the Fort Collins one for my layout next year.

John,

With the Super Streets track have you tried adding a 2.5 inch curve to curve straight track between all the D-21 curves? It might give you the clearance that you want.

I tried to use the P.E. trolley this past Christmas as a replacement for an older Lionel trolley on a Super Streets layout which had the 16" curves.  The old trolley worked great, the new one did not negotiate the curve.  It has rollers and they are spaced to far apart.
