Dual Gauge Primer


Think I'm nuts? Check out this Z/Zn3 turnout! Will not work with your average Marklin Lok, obviously.

accurate templates if printed on any printer that prints at 300 dpi.

I have not made this one yet, but they have been done.

This was my very first attempt, from about six years ago.
It is in use in my staging yard / test track, except for the dual to single
gauge transfer, which was scrapped after proving to be impracticle.
The ride through the points is a bit rough, but everything I have makes
it, except for the Kato Mikado, which hangs up going through facing
point on both my switches. The guard rails are too close on too tight
a radius for the long wheelbase. The rest of my switches will be #6's.
Hopefully that will correct the problem.

My second, better looking, more robust attempt.

#8 curved dual gauge turnout.
Main line on a 16" radius, diverging route on a 12"

One of my #5 switches built to the plans in the Nn3 Manual.
IMHO, this is a MUCH better template for laying these switches.

My curved dual gauge crossing. The dual gauge is on an
eleven inch radius, the narrow on a nine.
