We lead off with Amtrak 3 being led by AMTK 3 as it passes through Bernalillo, NM.
After a tragic derailment near Kingman, AZ, Amtrak 3 became Amtrak 4 in Flagstaff, AZ. Passengers were bused in from California and Kingman. Unfortunately, the train was still pointing west so BNSF 5836 was attached to the end of the train to lead it east.
In this video we see it approaching Albuquerque, New Mexico where the BNSF engine is removed and the train turned around; a process that added an additional 3 hours to an already 6 hour late train.
