A loaded CSX ribbon rail train traverses the, in-progress, Chesapeake, Susquehanna and Western RR on HARM night. HARM (Harford Association of Railroad Modelers) is a round robin group celebrating its 50th anniversary this year. Located in northeast Maryland, members meet every Tuesday evening. This train is based on the CSX prototype often seen on the nearby Philly Sub.
