Auburn was created in 1882 through the merger of two adjacent, competing railroad towns. Sheridan, initially established in the 1860’s, was threatened with abandonment in 1881 when the Burlington & Missouri Railroad (B&M) bypassed the existing town to build its own town, Calvert, only one mile to the south. The survival of towns during this era was dependent on the railroads. Sheridan, with the help of politician Church Howe and businessman Charles Nixon, attracted the Missouri Pacific Railroad (M&P) who built their depot less than a year later on the north side of Sheridan. Sheridan and Calvert subsequently merged in order to gain support for the acquisition of the Nemaha County seat. As a compromise, Courthouse Square was situated halfway between the two towns. Starting in the mid-1880’s, with two depots and the County seat, Auburn began to grow in a regional center for commerce.
