Thefts on trains in Los Angeles County may lead to Union Pacific not operating there, the railroad said in statements to the media Tuesday. The containers and trains are locked but can be broken into, leading to losses that range from $10,000 to $200,000 per heist, Union Pacific spokesman Jeff DeGraff told NBC4 Southern California. He also blamed lax prosecution of crimes that may have led to the thefts, including drug use and sales of stolen goods from railroad cargo containers.
