The PRR Middle Division in HO Scale will be open on November 7th from 3:00 to 6:00 p.m.
I am participating as part of a south-central Pennsylvania tour, which I organize, and we are open the weekend of November 7th-8th. The schedule is at http://svmr.pennsyrr.com.
In turn, the above tour is part of the annual PA/NJ/MD/DE Model Railroad Open House organized by Bruce Friedman. This year there are a record 137 model railroads open over the course of five weeks in November. Many of the railroads are Pennsy-themed. The full schedule is at http://modelrailroadopenhouse.com.
Hope to see you on the 7th!
