Purists will disagree that is an Ntrak layout. They would argue that the use of Kato Unitrack is not according to Ntrak standards. Also the set back on track from the sides of the modules appears to be less that the 2.5 inches stated in the Ntrak manual. Since it uses the Kato expanding track.
It looks as if there is a predetermined set-up, meaning that it's actually a sectional N-scale layout. Since these aren't actually modules, and they can't interface with NTrak modules, it has nothing to do with NTrak.
Yeah, I see lots of variations on layouts that are supposedly Ntrak. It seems the Ntrak standards are seen by some to be 'guidelines' to be considered but not adhered to.
I suspect that they are more interested in the cachet (such as it may be) of the NTrak name, than any standards. ;-) Say - if they're trying to get space at a show, it's much easier / safer to say they're NTrak than an independent, sectional N-scale layout.
Usually the big "for profit" shows will accept any layout providing they have room for it. But it is venders first so you have to get your application in early. Our club has supported the smaller local one day shows that benefit volunteer fire departments, model RR clubs (even if they are HO), a church, etc. We do not accept an honorarium from these groups like we do for the big shows. Basically we tell them (jokingly) that we will run trains for food. I've eaten some really nasty hotdogs in the process. Nothing like hotdogs left over from the bingo game that week.
I wonder...the NTrak manual recommends against sectional track, but does not rule it out. As well, the only requirement is compatibility with the Atlas track section for joining modules. Just saying, it might not be standard on NTrak, but neither is there any prohibition I can see.
Individual groups have often had their own rules, subordinate to N-Trak. Usually developed after time and experience.
