FREMO


The Friendship of European railway modellers is a modular rail transport modelling standard. Individual track and scenery modules are built to a common standard and are joined together to make larger model railway layouts.
The FREMO standards were created following a meeting in Europe in 1981.
Modules are wide, with variable length and viewable from both sides. Each module comes with adjustable legs, to create a uniform top-of-rail height of above floor level. Modules are physically joined together using three holes and hand-tightened M8 bolts with washers and wingnuts. The electrical inter-connection uses two Banana connectors per track bus, over which Digital Command Control signalling running at 14 volts is used for train control. Track uses Code 83 rails and fixed track centre-line spacing of ; representing separation @ 1:87 scale).
Some general aspects, such as rigid construction of modules, are derived from the Normen Europäischer Modellbahnen NEM 900 standards published by MOROP.
In 1995, the North American Free-mo standards were based on those of FREMO, with a number of changes made.
