Amtrak is planning to detour its southbound Coast Starlight between Oakland and Los Angeles in March and April due to track work. Instead of its normal route along the California Coast, train No. 11 will travel Union Pacific's ex-Southern Pacific route via the San Joaquin Valley and Tehachapi Loop. The detours are planned for March 13-15, March 24-30, and April 8-10.
Seattle departures of the train are one day earlier. Amtrak says that the track work may end early, so detours may not last all the way into April.
I've made reservations to take the loop on Sunday, 3/24 (leaving SEA Saturday, 3/23), since I missed this the last time it happened. PM me if you'd like to come along.
Edit: I got the dates wrong, but they've been fixed. See below.
