Amtrak trains stuck at snowy Donner Pass with nearly 400 riders trapped

SAN FRANCISCO (AP) — Nearly 400 people were trapped Friday when two Amtrak passenger trains were stranded in the snowy Northern California mountains after a large snow plow fell through the tracks, officials said.

Amtrak’s California Zephyr passenger trains were stranded near Donner Pass around 2 p.m. after a large plow being used to clear the tracks fell through a walkway and blocked the trains’ path, according to Amtrak spokeswoman Karina Romero.
