Oh, thank you. We're really into the PTC trolley, since here in Philly we actually see them still running on Girard Ave (and I think they used to run by our house back in the day).

Thanks. I wasn't sure how much flex track flexes, but I might as well go find out.
The boy and I just got started this year, so we've been learning a lot.

Thank you. We're in a South Philly rowhome, so space is always an issue. I'm thinking about making a micro layout, so I'm trying to determine just how micro it can feasibly be and work from there.
I've seen someone online using the 150 mm radius track. I suppose I could buy myself some of the 117 mm curve track and satisfy my curiosity that way, but I figured I'd ask if anyone had tried.

Has anyone ever run an N scale PCC trolley on 117mm radius Unitrack curves?
