I remember seeing the remnants of that old railroad when I was kid and I believe some of them are still there. There are bridge abutements where the Chartiers Southern Railway, if that is what it was, crossed over Chartiers Creek, kind of near where it crossed over Mc Murray Road (it actually crosses a creek right near the corner of McMurray Raod and Oakwood, my sister drove our car into it) and where it crossed over old route 19. Where the "bridge" over Chartiers Creek was, was pretty big and clearly branched off the exisitng railroad there. There was not a bridge there, just all the stone work. Also, for those looking for old tunnels, near there the old Montour Railroad crosses over Chartiers Creek and goes through an old tunnel.
