One other thing to note, is that the green cars have a plastic chassis - vs. the later metal one.

It's relatively easy to swap wheelsets, but not the chassis.

Dave -

I'm curious how you display this layout - do you park it and folks come out to see it in operation?

How about some photos?

Thanks Kevin - I was indeed considering going sharper, but suspected that the flanges become the controlling issue.  However, I've considered widening the track gauge on the curves.

Could you tell me what the minimum radius of the gas mechanical is?  I noticed someone earlier asked for info on minimum radius on all new engines and you said they were often still in engineering so it couldn't always be provided.

Also - do you ever produce/sell just the mechanism?  I'm sure a lot of folks would be interested in this one especially.  If so, how do I go about getting one?
