This branch was known as the King of Prussia Industrial Spur, It left the main line at North Abrams and followed the creek valley up grade to it crosses Rt. 23 (Valley Forge Road) it gose out through the Ind Complex till it crosses First Ave. it follows along American Ave. to a point where it has a switch and spurs off and the crosses American Ave. where it travels for about a 900 yards and has another switch where it crosses First Ave again to service a Company.
Back in 1976 the American Freedom train was parked up in there on display . The cars were spotted between the Today's Post Newspaper and The Sears Warehouse. Cars 30, 31, 32, 20, 33, 40, 41, 200, 201, 202, 203, 204 and 205 were spotted behind the Sears warehouse. The T1 locomotive, Aux Tender and the PNWC76 tool car were sitting on the industrial main and had to be moved when the Reading was switching cars into the industrial park. To provide for this, the T1 had to be kept under steam and ready for movement at all times.
Hope that helps,
