While still meeting all the applicable NMRA standards, these uniquely extremely accurate turnout templates are drawn to match the true prototype (AAR) turnout geometries and their consideable variable tie spacing.

Turnouts built to these diagrams appear much more realistic, because they do not continue to repeat the compromise curved switch turnout geometry of NMRA Recommended Practice RP12 and RP 13. The
NMRA Recommended Practice RP12 and RP 13 curved switch geometry was introduced by the NMRA way back in the 1940's specifically to allow train set manufacturers to more easily handle the then much cruder toy train locomotive chassis' and sharp curves of those times.

As well as being far more prototypically accurate, these templates include most of the missing major prototypical parts traditionally left off most other commercially mass distributed compromise templates. Thus it is now possible to hand lay, scratch build, jig build and/or kit build, authentic turnouts that actually look like the real thing.

Many different prototypically correct frog types can be used with these templates, so those will be shown separately later.

You can select which templates you wish to download from the appropriate table below. Many more turnout types and sizes are coming, so come back and check frequently, or email us, if the ones you want aren't shown yet. We have most recently added "N" Scale, "Z" Scale and "Electric Avenue" Tram/Trolley Street Track as extra tables below.
