Kato unitrack M2 + V1

[ntpntpntp]

As the other posts have said,  you can join other N gauge track systems to Kato Unitrack without the need for conversion / adapter pieces.  If the rail is code 80 (80 thou high) then it should be a good match, you'll just have to work out which rail joiner works best as some rails have a wider "foot" than others.

Here's Peco Setrack joining to Unitrack using Peco joiners (Unijoiner removed)


Here's Fleischmann Profi-Track joining to Unitrack using Fleischmann joiners which are a little loose on the Unitrack rail due to Fleischmann's wider foot.


You do have to keep in mind that the track geometry of the different systems probably won't match: different curved radii, different angles of points, different lengths of straight track etc.

Cheers, I'm from the Old South Wales valleys. If my mother hadn't  changed her mind in the old £10 days, I would be Australian now.

Ha Ha! It was actually 50 quid when I came out here. 

Regarding Tomix track,  @railsquid  of this parish is the man to talk to.
