I found 3 interesting B&O videos today, Googling around.
1) Aerial shots of ex-B&O coaling tower, Akron Ohio https://www.youtube.com/watch?v=gP7KZeQvscE
2) Maybe the same coaling tower (???) or at least a similar design https://www.youtube.com/watch?v=P8Piq498qF4
3) My favorite of the 3, is this 1990's awesome one of tower activity at B&O's “R” Tower, Cherry Run, West Virginia

Towerman Allen Brougham must have surely loved his job! I think he mentioned he had a 2-hour commute (each way) to go back and forth to work.
Apologies if any of these have been widely seen before. I had never seen them!
