611 in the valley

a few months ago the 611 went on the Buckingham branch line for train rides and me and my friend saw my friend chased it but i rode it and just for no reason the place i went for lunch was NEXT to the mainline and i walked to see the 2:30 pm train leave and saw almost 50 railfans and while riding the train i saw a BB high hood loco in a yard and still credit to my friend for the chase videos
