Amtrak SDP40F units 627 & 587 pull the eastbound SAN FRANCISCO ZEPHYR at Laramie. I was there waiting for the excursion behind Union Pacific 4-8-4 8444.
8,500hp of GE P42DC power brings eastbound California Zephyr #6 to a stop at the Martinez, CA Amtrak station. Leading is AMTK 147 followed by AMTK 41. Taken on National Train Day 2013.
Amtrak 6 exits Tunnel 40 deep down in Gore Canyon. If the view for the passengers down there looking up is anything like the view down then it is quite spectacular.
