As I have a lot of N Gauge stock from an abandoned project I want to experiment. I have some code 40 bullhead rail and some copperclad sleepering to suit. I came across some postings on another forum which suggests that the following works with MODERN N gauge stock: Track gauge: 8.85mm Flangeways: 0.8mm Check rail: 7.25mm ... Giving a back to back of 7.4mm?? I know that N track gauges seem almost impossible to obtain, so it seems like I will be filing various bits of metal until I get something to suit! I think the reason for narrowing the track gauge was to give the finer flangeways (still too big, but better than usual N gauge track). Two points: I am aware of 'FiNetrax' - which IS a big improvement, but if I go ahead with this (if it works!) I would like the flexibility of building track to suit. I like steam locos, so don't want to go down the route of rewheeling or building new chassis - I would like to run things 'straight out of the box' (or maybe go as far as tweaking back to backs). Can anyone suggest if the dimensions quoted will work (what I have read suggests it does) or suggest any refinements before I get the soldering iron out? |

Hi Steve, Impossible to say without knowing something about the wheels you intend to use, and whether you intend to use them as supplied or modify the back-to-back or mix different types on the same track? At first sight you dimensions conflict with the NMRA standards for N gauge, which have the back-to-flange dimension at 8.2mm MAX. You have a check gauge of only 8.05mm, so there is a possible conflict there. I don't know anything about N gauge, so it's possible RTR wheels are normally at the bottom end of the NMRA range, or comply with the pre-2010 dimensions, as for 00. What is the problem with the existing N gauge standard? Or do you want to use 2mm Association wheels on the same track? regards, Martin. |
