The AFE project files contain detailed information about construction projects and equipment orders undertaken by the Western Pacific Railroad between 1911 and 1983. The indexes to AFEs are useful in providing a summary of this information.

All railroads had a system for approval of capital expenditures by senior officers or, in some cases, by the board of directors. On the Western Pacific this approval process was known as Authority for Expenditure (AFE). Department heads, senior officers, the President, or the Board of Directors would propose capital expenditures as necessary to build new structures and other facilities such as depots, shops, and team tracks, to replace worn or obsolete equipment, upgrade track and structures, to buy locomotives and passenger cars. Each item or project was assigned an AFE number by the Finance or Accounting Department.
