Keystone Free-MO

Location: 
Harrisburg-York-Baltimore corridor Pennsylvania and Maryland

Keystone Free-MO is a HO scale modular model railroading group. The group's modules depict Pennsylvania Railroad rights-of-way circa 1954. The group favors the Pennsylvania Railroad road name, but also welcomes members with an interest in its successor lines -- Penn Central, Amtrak, Conrail, Norfolk Southern and CSX.

The group follows the Free-MO standard for module interfaces, and will focus on meets at the Great Scale Model Train Show in Timonium, Maryland.
