Nice video! I like the electronic signal change at 1:30.
Do you know what that maintenance train was? There was a lot of smoke/steam coming from the undercarriage of the locomotive at 2:15.

That is a Rail Head Treatment Train (RHTT). It cleans the rails this time of year with all the leaf fall, to help adhesion.
