T-TRAK is a relatively new modular standard in the hobby of model railroading, which uses modules 2 3/4" (60mm) high, which rest on a table, such as a banquet table.

T-Trak is based on a particular track product, namely Kato Unitrack. Kato Unitrack has joiners which are quick to connect and disconnect to the adjacent track. The tracks are fixed to the base, and the joiners join the modules as well as the track.

History of T-trak
T-Track was developed in Japan, but was popularized in the US by Lee Monaco-FitzGerald. It has become popular, because it can be constructed in a small space, and layouts can be assembled on a table the size of a banquet table or even a dining room table. Clubs such as Cub Scouts have made layouts where each member makes a module and they are put together at meetings, thus allowing each member to contribute while the operation is the result of the collaboration of all members. Modules can also be set up at senior centers or church halls for temporary demonstrations.

T-trak standards
T-trak was originally designed for N-Scale, but there are also standards for HO scale, as well as other scales. There is a large group of HO T-trak modelers in Australia. The center to center spacing of two tracks in N-scale can be either 25mm (1") or 33mm (1 5/16"). Most modelers use the 33mm spacing to accommodate longer cars and locomotives.

In HO scale, track centers are 60mm (2 3/8".

Single Module size for N-Scale is 12 1/8" wide by 8 1/4" deep. Corner modules are 14 3/8" square.

For HO scale the single modules are 19 1/4" wide by 28" or 20" deep. Corner modules are 28" square.
