Columbia
Columbia is the only prototypical (based on what actually existed) area of the layout. The time era of Columbia is 1920-1940. Columbia covers approximately 200 sq.ft. of the layout, and is home to a large roundhouse facility, a major yard, coaling and diesel facilities as well as two railroad stations (Pennsylvania RR and Reading RR). Most of the buildings here were scratchbuilt to scale. AutoCAD drawings were created based on old photographs. While some buildings are still standing, others were torn down over time.
The photos below were taken March 8, 2014. Locust Street is now complete and several backyards have been scenicked. Next, I turn my focus to Second Street between Locust and Cherry Streets.
