I think the Starlight is fairly safe. UP uses this ex SP mainline as the mainline from California to The Pacific Northwest. So they will fight to get it back open unlike the two Canadian examples of shortlines on money losing branches.
It'll be back.
This also reminds of last year's outage of the bridge damage that took almost 3 weeks to repair. I'm going to assume that UPRR will do everything it takes to reopen the route segment as soon as it is possible to do so. This and last year's bridge damage incident would be dwarfed when compared to the Oakridge mudslides 10 years ago.
I agree. This is Union Pacific's main north-south route along the west coast. They will reopen it quickly. The Chaluer was running on a railroad that had absolutely no freight traffic, so there is no incentive to get it back in service. The Hudson Bay route was split by a disaster and it looks like there is no company interested in restoring the route, since the port at the end of the line is now handling very little freight. There's no comparison between the Coast Starlight route and the Canadian trains.
Comparing the CS to the ill-fated Canadian services is comparing apples to oranges. As for the Hudson Bay, a trainset is trapped in Churchill.
