Hello does anyone have any pictures of th Boston and Maine in Rochester NH during the 1950 to 1980 range that they would be able to share? Thank you.
Dstarr might be able to help you.
Also if you are a BMRRHS member you can go to their archives in Lowell, Ma. They should have many photos that should be able to help you. All of my photos from the era you stated are from copyrighted publications.
The 3 Boston and Maine books by Robert Willoughby Jones have excellent photos from across the B&M system. You can generally find them at most New England area train shows (HUB and Amherst shows). Check with Ron's Books. They will likely have good recommendations.
