(I’m working with Code 80) I find Peco flex track infuriating to work with. Yes, its semi-rigidity is nice for straight runs of track, but apart from that, I find it very problematic to work with. I bought some, figuring it’s rigidity would cause it to hold a pre-formed radius, and make it easier to work with. Well, it springs back plenty (even when trying to bend it to the modest 22” radius of my main line). And because of the springback, I have to re-curve it numerous times when cutting and test-fitting. Invariably, because both rails are allowed to slide in the ties, the groups of ties work themselves farther apart, which creates an annoying tendency for ties to work off the ends of the rails. (The positive capture of one rail, a la Atlas flex track, prevents this) The rail-holding portion of the ties is overly delicate, as well - I have yet to escape the curse of an inch or two of rail popping free from the ties when filing the end of a clipped rail. The type of file I use is officially classified as a “woo woo woo” file, (of unmarried parentage, if that word doesn’t make it past the filter), but I’m thinking it ain’t the only one in the room when I’m having to jack around with Peco flextrack. And then comes the necessary exercise of sliding the rail back though enough ties, so I can slide it forward again to thread it back through the little hold-downs. I’ve never had to do that with Atlas. It’s gonna be one dern bad time if a rail escapes captivity after its affixed to the layout. I’m not some dang modeling brute, nor an impatient sort. I used to do wooden model ships (and still may again, someday), no kits, get on the phone to the Smithsonian (yep, really) and order a set of ship’s drawing, hand select my lumber and go to work. I can turn out a hundred identical belaying pins by hand with a sub-toothpick-sized bit of exotic wood chucked up in a moto-tool at just one end, with a file. I’m patient enough to re-rig or re-tension an entire set of backstays and forestays to eliminate any curvature from a mast. But this Peco flex track makes me regret my life decisions. So how about it? Does Peco flex track offer some unique benefit(s) that I’m not seeing, that make it worth the ills suffered during preparation and installation? Is there some way to ameliorate the difficulties of working with this stuff? I think nothing of pre-joining two pieces of Atlas flextrack together, to eliminate some of the track end-clipping, but the higher likelihood of rail popout due to handling a larger, more unwieldy piece (combined with the captured rail joiners in the middle making sliding the rail more difficult), just dissuade me from going that route with Peco.
