NMRA Introduction to Module Standards and Recommended Practices.

INTRODUCTION TO MODULE STANDARDS & RECOMMENDED PRACTICES - NMRA Bulletin March 1990 - These standards and RPs have been assembled from data sent in from module groups that are actively building and operating these units in all parts of the country. It is clearly indicated that there are two distinct types of operation desired so we have set up two separate sets of figures in order to accommodate both groups.

WHAT IS A MODULE? A module is a portable section of table type structure which is but one part of a large group of like tables which when all assembled together form a large and fully operating model railroad. They are built by individuals as part of a home layout or specifically for use interfacing with others in a large setup. All are built to a set of standards that allow each unit to interface exactly with other units anywhere in the overall system. A module may be a single table or a group of tables which must be capable of interface at each end but may deviate between these ends so long as the type of operation is not compromised or restricted. By being portable, they may be disassembled for transporting to conventions or public displays. Many clubs are formed for the specific purpose of building module layouts as space for a permanent layout is hard to find and is very expensive when available

WHAT IS A SECTIONAL LAYOUT AND HOW DOES IT DIFFER FROM THE MODULE TYPE? A sectional layout is built in a similar manner but each unit is constructed to fit in a specific spot in the overall layout and will not fit in any other place. As new units are built, they must be designed to fit in a particular place and will not interface anywhere else. Some sectional layouts may be built to NMRA standards but most are to a set of figures agreed upon by the group as interface is not a factor to be required.
