NS 21T is led by sweet Conrail blue, as it exits Rockville Bridge at 17:19 on track 2. Canon 20D and 70-200mm lens, 1/400 sec. exp., f7.1, F.L. 165mm, ISO 100.
With the river at 3 feet, I am standing on exposed rocks about one hundred feet from the west shore, as NS 10N, powered by NS 8396 and UP 4799, covers most of the length of the bridge.
