Fairly short trains for the Milwaukee but I also think they were relatively new trackage rights per the BN Merger if I am not mistaken.
Suprised the Short Amtrak trains had domes, but not the Coast Starlite.
Not a fan of ‘sound dubing’ film that was shot without sound.
Not really. SP was not a big fan of domes, the 3600-series dome-lounge rebuilds had a tighter clearance profile, allegedly to fit the snowsheds over Donner Pass. All sorts of requirements were insisted upon by SP to allow regular-height domes on their routes so domes didn’t show up on any SP routes.
I recall that at least once when the California Zephyr was detoured over the SP the passengers were not allowed to be in the domes for at least a part of the trip.
We lived about 4 miles north of Napavine with the RR about 1200 feet away, and 150 feet below us. Always enjoyed the sounds, but could not see the trains. A BNSF engineer gave a program at our church, and the difficulties of getting a long train up the Napavine hill when going north in wet weather. The elevation rise going south was a better grade. We always enjoyed the varying sound, changing with train direction, weather, etc. Very much enjoyed the video
With all of SP’s tunnels and snowsheds, maybe they were afraid of icicle strikes on the domes.
SP mounted ice breaking appratus to their engines that operated in the area with dome cars in their consist.
The GP38-2’s that are assigned to snowfighting service over Donner Pass are equipped with icicle breakers, among other things.
I knew some railroads used roof mounted ice breakers, but I don’t recall seeing any on Amtrak locos.
