Model Information: With Tracksetta you can make sure your straights are really straight and your curves are smooth without any kinks or sudden changes of direction which make derailments inevitable. These simple but effective tools are a worthwhile investment since well laid track is essential for reliable running.

Road Name History: Can't have model trains without track can we? The track on a railway or railroad, also known as the permanent way, is the structure consisting of the rails, fasteners, railroad ties (sleepers, British English) and ballast (or slab track), plus the underlying subgrade. It enables trains to move by providing a dependable surface for their wheels to roll upon. For clarity it is often referred to as railway track (British English and UIC terminology) or railroad track (predominantly in the United States). Tracks where electric trains or electric trams run are equipped with an electrification system such as an overhead electrical power line or an additional electrified rail.

Rail codes:
The code refers to the actual height of the rail. The followings heights are used for N-scale:
- Code 80 = 0.080" tall or about 13" N scale height - the mostly used for sectional tracks.
- Code 70 = 0.070" tall or about 11" N scale height
- Code 55 = 0.055" tall or about 9" N scale height - the mostly used by modelers wishing a realistic effect for their layout. Can be used with all modern rolling stock (low flange wheels).
- Code 40 = 0.040" tall or about 6" N scale height

Turnout codes:
The turnout number describes the length needed for the diverging track to be 1 foot apart from the straight one . So the lower the number, the sharper the curve, and the higher the number, the more gradual curve on the diverging track.
- In a #4 turnout, the rails are 1 foot apart at a distance 4 feet beyond the frog
- In a #6 turnout, the rails are 1 foot apart at a distance 6 feet beyond the frog
- In a #8 turnout, the rails are 1 foot apart at a distance 8 feet beyond the frog
Note that European brands such as Minitrix or Fleischmann use a different notation for turnouts and refer to the radius of the curvature of the diverging track.
