Abraham Lincoln signed the Pacific Railway Act of July 1, 1862, creating the original Union Pacific. One of America's iconic companies, UP celebrated its 150th anniversary in 2012. Today, Union Pacific Railroad is the principal operating company of Union Pacific Corporation (NYSE: UNP), linking 23 states in the western two-thirds of the country by rail and providing freight solutions and logistics expertise to the global supply chain. Ad we tell our story through a new, interactive timeline.

As part of the sesquicentennial celebrations, UP sponsored a contest to remake the iconic "Great Big Rollin' Railroad" commercial. We also invited our valued civic partners to join in the celebration, by telling their histories through Union Pacific’s "Train Town USA" registry.
