Though not as well known as it's logo featuring the Capital Dome, this logo could be found on B&O's trailers when used in "Trailer Jet" service. One such example has been preserved at the B&O Railroad Museum. This one's for you, Frank!
All those shots of interesting railroad details, what you see trackside, up close and personal! Excludes shots going into my other albums: "Engine Details," "Signal Details," and "Switchstand Shots."
