When the Houston & Texas Central (H&TC) Railroad built through Dallas in 1872, the town was just another rural community in north Texas. By 1886, when the Katy Railroad entered Dallas from the north under the charter of the Dallas & Greenville Railway, Dallas was developing into a major rail and transportation center on the banks of the Trinity River. The two lines crossed a few miles north of downtown Dallas at a location that became known as Highland, sometimes spelled "Hiland". Both lines moved significant traffic through the diamond, and in 1904, Tower 35 was established to interlock the crossing. Some years later, Mrs. Baird's Bread Co. built a bakery southwest of the junction, and later, the Dr. Pepper Company built its headquarters northeast of the junction. A rail siding next to the Dr. Pepper building was known as "Oasis".

As Dallas continued to grow, the H&TC tracks through downtown became a safety and traffic congestion problem. In 1926, the Dallas Belt Line was built to permit the Southern Pacific, successor to the H&TC, to bypass downtown. The former main line was relegated to secondary status and then eventually abandoned between downtown and Tower 35. After World War II, the H&TC right-of-way was used for the construction of Central Expressway, one of the first freeways in Texas. In 1950, Tower 35 was decommissioned, and in the early 1990s, the Katy line was taken out of service by successor Union Pacific.

Today, the former site of Tower 35 is occupied by the Mockingbird Station of the Dallas Area Rapid Transit (DART) system. Portions of the former rights-of-way of both railroads are now used by DART north and east of the station.
