The Sacramento Bee says gun rights advocates pushed for an order by Congress to reverse a near decade-long gun ban on Amtrak trains.
Beginning Dec. 15, guns can be brought aboard trains that have checked baggage service. Gun owners must inform Amtrak officials 24 hours ahead of departure and unloaded firearms must be packed in hard-sided containers for storage in train lockers.
Cars are being retrofitted with weapons storage lockers.
The gun allowance applies to most Amtrak trains, including the San Joaquin service connecting Sacramento to Oakland and the Central Valley. The gun ban remains in place on Capitol Corridor trains connecting Auburn, Sacramento and Davis with the Bay Area.
