The Trinity and Brazos Valley Railway (reporting mark TBV) of Texas came into existence on October 7, 1902, originally chartered to build a railroad from Johnson County to the Beaumont area near the Gulf coast.
Financial problems in the system led to its purchase by Colorado and Southern Railway (C&S) on August 1, 1905.
Benjamin F. Yoakum, a railroad executive who was a director of the C&S, was contracted to build more track in Trinity and Brazos Valley system.
As part of the construction deal, C&S sold one-half of the securities issued for the project to Chicago, Rock Island and Pacific Railway (CRIP), making the T&BV half-owned by both CRIP and C&S parent Chicago, Burlington and Quincy Railroad.
T&BV contracted with the Missouri-Kansas-Texas Railroad (MKT) between Waxahachie and Dallas, while it used Gulf, Colorado and Santa Fe Railway (GC&SF) tracks on its northwestern end between Cleburne and Fort Worth and on its southeastern end between Houston and Galveston.
