Funny you should say that because I left my appointment in Westwood and drove to North Billerica thinking I'll catch SOMETHING there.
I get off 495 and theres a freight train going under the bridge. I beat it to North Billerica and there was a commuter rail train pulling in as I pulled up. So I missed filming that but I immediately caught the freight! 17 cars too, bigger than anything that passes through woburn these days. I guess I was just lucky. I wish I were a minute or two earlier so I could have filmed them both. This station is very well lit, great for after sunset filming!
