On May 18-19 the National Capital Trackers celebrate National Train Day with a 2-day show at the Chantilly, VA Public Library. The Library is located at 4000 Stringfellow Rd., Chantilly, VA. Of course we know the real National Train Day is May 11, but the deferred observance enables us to put on a 2-day show while not interfering with Mothers’ Day. Show hours are 10am-5pm Sat., 1pm-5pm Sun.
