Beautiful color shot of two iconic B&O locomotives.
I have one quible though. The location is identified as "the Potomac River narrows west of Cumberland, Md., on Baltimore & Ohio’s main line to Pittsburgh". All of that is correct except for the name of the watercourse which the line follows. It is actually Wills Creek, a tributary of the Potomac, that the Pittsburgh Division follows north towards Sand Patch. The Potomac itself curves to the southwest at Cumberland. The B&O's "West End" follows it towards Keyser, WV.
