The Buffalo Bayou, Brazos, and Colorado Railway (B.B.B.C. or B.B.B. & C.), also called the Harrisburg Road or Harrisburg Railroad, was the first operating railroad in Texas. It completed its first segment of track between Harrisburg, Texas (now a neighborhood of Houston) and Stafford's Point, Texas in 1853. The company established a western terminus at Alleyton, Texas prior to the Civil War. The railroad was sold after the war and reincorporated as the Galveston, Harrisburg, & San Antonio Railroad. This right of way was acquired by the Southern Pacific Railroad and is today a property of the Union Pacific Railroad.
