Landslides along a section of Burlington Northern Santa Fe railroad track just north of Vancouver, Wash., mean Amtrak is using charter buses to move travelers between Portland and Seattle until Thursday.
Three landslides have hit the area in recent days, the latest on Monday evening.
BNSF spokesman Gus Melonas says a 48-hour moratorium on passenger rail travel is instituted after a landslide.
Amtrak spokesman Marc Magliari tells the Columbian that passenger traffic on the north-south route is expected to resume Thursday morning.
Melonas says cliffs in the area have been saturated by heavy rains.
