Today we're at the end of the MBTA Orange Line for a full ride trip to Forest Lane Station. Towards the end of the line, I notice my car's "R-46 style" air compressor kicks on reliably after each stop, so I attempt to get a couple good audio clips of that happening. I got close, but it's far from perfect. Enjoy the video!
