The Burlington Northern Santa Fe railroad plans to invest $3.9 billion in upgrades to its network this year.
The railroad said Wednesday that its capital spending plan is $400 million bigger than its 2011 budget of $3.5 billion. Overall, the nation's major freight railroads, which include BNSF, plan to spend about $13 billion this year, up from 2011's $12 billion, as the economy improves.
BNSF says most of its spending _ $2.1 billion _ will upgrade its core rail network. Another $1.1 billion will be spent on locomotives, freight cars and other equipment. About $300 million will be spent on developing the federally mandated system to remotely stop trains headed for a collision.
The Fort Worth, Texas, based railroad is owned by Warren Buffett's Omaha-based Berkshire Hathaway Inc.
