About the Susquehanna Division

The National Model Railroad Association (NMRA), a 501(c)3 not for profit educational organization, was founded at the first National Convention over Labor Day Weekend, 1935. The initial goal was to develop standards for scale model railroad equipment to facilitate interchangeability and operation of equipment between modelers, clubs and others.


Today, the NMRA is a world wide organization, with over 18,000 active members, associates, families and clubs dedicated to the hobby of scale model railroading in all it’s facets, supporting a hobby of many diverse interests that all relate to the greater world of trains and railroads.


The Mid-Eastern Region (MER) is one of 19 Regions within the NMRA.  The Susquehanna Division, the sponsor of this website, is one of 10 active divisions within the MER.  With several prior divisions being reorganized over the years the Susquehanna Division is assigned #11.


All NMRA members residing in the counties within the Division are automatically part of the Susquehanna Division #11.  There is no additional fees or paperwork required.
