The Frelanced South Erie, Titansburg, and Iriton RR, will be an industrial railroad that serves various industries in northwest PA, and northeast, OH including a Lake Port, fully integrated Steel Mill, cement plant, and many smaller industries including some in Erie, PA. 

I also have a walthers Double Track Truss Bridge, and Micro Engineering City Viaduct, all assembled and was used in a scene with an elevated mainline.  Some of the mainline on solid ground with concrete retaining walls, other parts with the viaduct and double track truss bridge to cross over a competing RR's tracks and roads.

I was wondering if I could create such a scene in Erie, with the South Erie, Titansburg, and Iriton RR crossing under the double track mainline.  From what information I have, the NKP and NYC were single track lines.  But the PRR also was in that area and I am hoping it had double track through that area so that I can have the double track line as the PRR.  Or is there another railroad that was in that area that could or did have double track in that area in the early 1950s? 

Thanks!
