Amtrak's Phase IV Heritage Unit #164 bypasses the fairly new Georgetown I.T. track. This siding was re-laid parallel to the mainline in order to make room for the Maryland Department of Transportation Purple Line Project. Construction can be seen to the right of the train.
Lots of acton one of the busiest - and fastest - sections of the Northeast Corridor plus the Capitol Limited going through Harpers Ferry, Sand Patch Tunnel and more.
