Slim Rail Modular Group

Modular HOn3 Club


Slim Rail is a group from the Colorado Springs, Colorado area modeling the historic Colorado narrow gauge railroads in a portable (modular) configuration.  Slim Rail has two divisions within the same club - one group modeling in HOn3 the other in On3.


Each club member can build their own privately owned module based upon specific standards.  These standards allow all modules to be linked as one large operating layout.  We set up our modules at various events throughout the region to promote our rich railroading history and the hobby of model railroading (please see our show schedule below).  Many of our club members are national award winning modelers and authors.  We are also a 100% NMRA club.
