The Kato Unitrack Concrete Tie Double Track is completely compatible with all previous Unitrack offerings. The Double Track curves pieces feature “Superelevated Curves” which means that they are tilted to create a realistic banked shape. This does mean that “Erasement Curves” are required to connect the superelevated curves to regular flat track (either double track or standard Kato Unitrack). “Erasement Curves” are superelevated on one end (marked by a triangle on the underside of the piece) and flat on the other. They act as “adapters” for the superelevated curves.

Model Information: Unitrack is a range of sectional snap tracks with integrated ballasted roadbed. Turnouts are all fitted with electrical motors located under the roadbed and ready to be operated. Unitrack is the basis for the T-Track modular standard.

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.

Brand/Importer Information: Kato Precision Railroad Models (関水金属株式会社 Sekisui Kinzoku Kabushikigaisha) is a Japanese manufacturer of model railroad equipment in N and HO scales. The Tokyo-based company manufactures models based on Japanese prototypes (such as the Shinkansen bullet train) for the Japanese market, North American prototypes for the North American market and European high-speed trains for European market.
The Kato (pronounced kah-toe) model railroad companies were founded by Yuji Kato, father of current president Hiroshi Kato, of the parent company Sekisui Kinzoku Co., Ltd.

The design and distribution of models for the North American market are handled by their U.S. subsidiary, Kato USA, located in Schaumburg, Illinois.
The design of special models for the European market is handled for some of them by their partner, Lemke, whereas the general distribution of Kato products in Europe is handled by NOCH; both companies are located in Germany.
As a result, some Kato European models are sold as Kato Lemke and others as Kato (alone).
