On January 24, 2006, BNSF announced a $2.4 billion program of infrastructure upgrades for 2006. The upgrade program includes: double- and triple-tracking of track and a second mainline track through New Mexico's Abo Canyon on the former ATSF transcontinental line; expanding the Lincoln, Nebraska, classification yard and double- and triple-tracking of track in Wyoming's Powder River Basin region; expansions at eight of the railroad's larger intermodal facilities, and extending many sidings and expanding and improving refueling facilities. In making the announcement, BNSF chairman Matthew K. Rose cited improvements in the company's return on invested capital, and expressed hope for continued improvement. In March, 2008, the railroad was completing the triple-tracking of Cajon Pass in California, creating four tracks through the pass—three BNSF (former Santa Fe and newly installed) and one Union Pacific (former Southern Pacific).
