The H & BV bought the rights to the Velasco, Brazos and Northern Railway, which then consisted of 20 miles between Anchor and Velasco. Its 1924 acquisition by the New Orleans, Texas & Mexico was followed a year later by the latter's purchase by the Missouri Pacific. But the H & BV operated as a separate company for several decades more.
