The Minersville Branch (PRR) began at Nichols St Yard in Pottsville and ran west for about 5 miles to Lytle, PA, which is just west of Minersville. The bridge peers in Minersville are still intact where the line crossed (overhead) the river and the Reading Company tracks. If you travel west on Front St going out of Minersville you can see a piece rail where the Minersville Branch crossed the street at grade. Look for the welding company and the Duncut Hose Company on the far side of the street. The ROW ran between them and is still visible and can be walked without any difficulty all the way to where Shaffer's Hill Road makes a sharp left turn. From that point to the end of the branch is hard to follow as the landscape has been majorly disturbed.
I have a niece collection of PRR books with many pictures, but only one is on the Minersville Branch. The picture is of a BS24M (Baldwin center cab road switcher and a caboose - or cabin car in PRR terminology) at a point not identified.
Hope this is helpful. Contact me if you need more information.
