A VRE commuter train pushes towards DC past the marina. The double white lines are from the light coming from the windows of the double deck cars, while the red is from the marker lights on the pushing engine. Note the eerie shadows on the boat from the many mooring posts, casting shadows from the many point sources of light, as the many piers have walkway lighting.
My other Neabsco shots are 386581 (also night), 385873 (sunrise) and 374972.
