A train stuck overnight in the Northern California mountains resumed its journey Saturday after a snow plow that was blocking the tracks was removed, officials said.

Two Amtrak trains and about 400 had passengers were initially stranded after the accident Friday. One train was pulled to Reno, Nev., and its 165 passengers were put up in a hotel, Amtrak spokeswoman Karina Romero said.

The other train, which was headed from Emeryville to Chicago, remained in the mountains until the tracks were cleared Saturday morning.

About 60 passengers from the second train were taken by bus back to the San Francisco Bay area overnight, while 155 stayed on board to wait for the line to reopen, Romero said.

The train had heating and lights and passengers were given food, Romero said. No injuries were reported.

The train was scheduled to arrive in Chicago Monday morning about 16 hours behind schedule.

A Union Pacific spokeswoman, Zoe Richmond, confirmed that the company's equipment was blocking the tracks but had no other information.
