One solution for a large-scale layout is a train table. Unfortunately most are too large to easily transport and quite difficult to reach across. A few could be clamped together to create a larger table, but a flush edge is needed to facilitate running tracks between tables. Since few homes and apartments can accommodate a large train table in the middle of the room, narrower train tables are a more practical alternative.

Model railroad clubs have developed a number of solutions that can be adapted for wooden railways, including modular segments. These facilitate transporting large layouts and allow reconfiguration - even collaboration between model railroad clubs or families with compatible segments. An alternative strategy for limited space and accessibility is a narrow shelf railway that provides access to all tracks from one side - critical when the layout is against a wall instead of monopolizing the room’s center.

 Unable to find any mention of narrow wood track tables or wood track modules, I submit the following ideas and dimensions as a standard - suitable for both portable tables and shelf railways...
