The Latest on an avalanche that has shut down Amtrak's California Zephyr passenger train service between Reno and Sacramento, California (all times local): 15:30.
 
Amtrak passenger train service between Reno and Sacramento is unlikely to resume Thursday and may remain suspended Friday because of a fierce winter storm.
 
Service on the California Zephyr was suspended Tuesday after an avalanche sent snow onto the Union Pacific tracks in the mountains west of Truckee, California, where more than 4 feet (1.2 meters) of snow has fallen over the last two days.
 
Amtrak spokesman Marc Magliari says westbound travelers on the route from Chicago to the San Francisco Bay Area in Emeryville, California, will be housed Wednesday night when they arrive in Reno.
 
They'll ride charter buses to Sacramento Thursday, and board a train to Emeryville.
 
He says similar transfers are likely on Friday.
 
Eastbound travelers from Emeryville will transfer to charter buses in Sacramento bound for Reno, where they'll board a Chicago-bound train.
