Photograph of International & Great Northern railroad crossing in Round Rock on U.S. Highway 81 (old designation). September 1936. Location of January 22, 1927 accident – A bus carrying the Baylor University basketball team to a game at the University of Texas at Austin takes a grade crossing just as an International-Great Northern train approaches. Evasive action is taken, but the bus skids on the rain-soaked road surface directly into the path of the train. 10 players are killed, 12 injured. To this day Baylor honors them as the "Immortal Ten." The overpass constructed there was dedicated to the ten students.
