Track uses Code 83 rails (2.1 mm or 0.083 inches high), with a minimum curve radius of 2,000 millimetres (6 ft 7 in; representing 175 metres or 575 feet at 1:87) and fixed track centre-line spacing of 46 millimetres (1.8 in; representing 4 metres or 13 feet separation at 1:87 scale).

The
Australian Model Railway Association has a set of standards based on FREMO called the "AMRA Free Form Module Standard." Version 2.4 of the standard was published in July 2024. As of 2024, there are standards for HO and N Scales, with an O Scale version under development in collaboration with the

Single track modules are 500 millimetres (20 in) wide, of variable length, viewable from both sides. Each module comes with adjustable legs, to create a uniform top-of-rail height of 1,300 millimetres (51 in) above floor level. Modules are physically joined together using three

In 2004, the traditional Free-mo standard was adapted for N scale (1:160). It uses Code 55 rail at a nominal height of 50 inches (1,300 mm). Curves should not have a radius of less than 22 inches (560 mm) on the main line and use turnouts sized
