Many non-LEGO model railroaders have standardized track module standards allowing for interchangeability of (often highly-decorated) track sections (due to availability, damage, scheduling, etc.) as well as quick set up and breakdown of layouts at meetings and conventions. For example, most of the N-scale model railroad clubs in my area adhere to the NTRAK standard. One can make their own custom 4'x2' module at home and "just show up" at a meeting and expect to connect to the organization's layout that day. Similarly, if someone drops the club's Police Station module and damages it, a spare Quarry module that someone happened to have in their trunk can be swapped in as a substitute with only very minor assembly work (mostly plugging things in).
Is there anything resembling a standard module size or configuration among serious or organized LEGO railroad hobbyists?
