What it does
The company states that Union Pacific Railroad Company is its principal operating company and a Class I railroad in the U.S. It runs an integrated rail network that links Pacific Coast and Gulf Coast ports with Midwest and Eastern U.S. gateways, with corridors to Mexican and Canadian gateways. The filing says the railroad provides freight transportation across three commodity groups: Bulk, Industrial, and Premium. It treats the railroad and its subsidiaries and rail affiliates as one reportable operating segment because the rail network is integrated.
