There are several videos of the AAPRCO Pine Tree Limited special train (3 Amtrak locomotives and 26 private cars including former B&M sleeper SALISBURY BEACH), operating to and from their convention at Portland ME, on the former B&M in September 2014. This page from the public area of the AAPRCO website has links to 9 of these videos which are posted to YouTube by various people. One of them is shot from a quadcopter which provides a unique aerial perspective.
