Two crossings of the International & Great Northern Railroad and the Houston & Texas Central Railway
The town of Bryan was founded in 1859 by landowner W. J. Bryan when he donated land for a town site to the Houston & Texas Central (H&TC) Railroad as they built north through the area. Construction was halted south of Bryan (at Millican) during the Civil War, but eight years later, the railroad finally reached the town. Texas A&M College was opened in 1876 south of Bryan at a location that became known as College Station, named for the railroad station used by college students. In 1901, the Calvert, Waco & Brazos Valley Railroad built south from Valley Jct. to Bryan as part of a plan to connect Waco with Houston. The International & Great Northern (I-GN) Railroad took over the construction effort and completed the line south from Bryan through College Station to Spring in 1902. The I-GN line paralleled the H&TC line through Bryan and College Station, crossing the H&TC line twice -- at the south end of College Station, and near downtown Bryan. Towers were constructed at both locations, Tower 7 in College Station and Tower 36 in Bryan. Years later, the I-GN became a Missouri Pacific (MP) property while the H&TC became part of Southern Pacific (SP). In 1965, MP and SP agreed to share the SP line south of College Station to Navasota and the ex-I-GN line was abandoned between Tower 7 and Tower 9 (Navasota). Tower 7 was retired at that time and the parallel lines through College Station and Bryan were operated jointly as a long siding, a situation that continues today under Union Pacific ownership, successor to both railroads. North of Tower 36, the ex-I-GN line curves west heading for Valley Jct. and Waco while the ex-H&TC line continues north to Hearne. Tower 36 was dismantled and the interlocker has been converted to an automatic system.

the railroad crossing adjacent to Kyle Field. Note the tower was near the baseball grandstand on the map and in the image above.

We contacted the Bryan/College Station public library to see if they had any info on Towers 7 and 36. This was their response:
We searched the early day newspapers and found a couple of mentions of the interlocking towers--no pictures. In the Bryan Eagle of April 28, 1904 on page 5 reads "Having begun operation of the tower switching system, Messrs. Vick and Batts asked an Eagle reporter to say to the public that all spectators are required to remain outside the operating room. A reasonable number of visitors may go upstairs, but must not pass inside the railing where the levers are worked. If these rules are violated they will be forced to lock all visitors out altogether." In the Bryan Morning Eagle of Feb. 22, 1903 on page 3 reads "Charles Smith in charge of the works here went to College Station today to put into operation the interlocking switch plant recently installed there. The state railroad commission is to be present at the test to pass officially on its efficacy. Navasota Examiner."
