This route that goes through Harper's Ferry through virgina and Maryland is a great and beautiful route. It's big for rail fans and I've visited there multiple times. There is a station at Harper's Ferry and route goes through a tunnel and bridge that goes over river. There is old trussel bridge that goes through the national park that CSX still uses. There are videos on YouTube for Harper's Ferry rail. The route also goes through the Y at point of rocks. I believe this will be a great suggestion for both passenger (MARC and P42 amtrak) and freight (main CSX). I believe it goes through georgetown MD as well.

From someone else's comment: The route should include a P42DC, CSX ET44AH or ES44AH (including the new heritage units), SD70AC, CW60AC/ES46AC, SD40-3, and/or GP40-3.
