Here's a direct link to the video mentioned: Wish there was better footage therein of that black and yellow F unit that's coming thru the Winslow Tunnel.
I wasn't sure if this was the Winslow Tunnel, thanks for posting! Agree, the footage of this video could have been better.
Neat film - talk about a late-first generation diesel amalgam of units. It looks like there was a cab unit in O/W and what I think might have been a GP-7 still in black and yellow. Best Regards,
