Crossings of the International-Great Northern, Houston & Texas Central, and Gulf, Colorado & Santa Fe railroads

Navasota is one of the oldest railroad towns in Texas, becoming a major rail junction with the intersection of three lines. First to arrive was the Houston & Texas Central (H&TC) Railroad in 1859, building north out of Houston, the first major north/south railroad in Texas. The Civil War disrupted progress, but by 1873, the line was complete to Indian Territory (Oklahoma). The H&TC was eventually acquired by Southern Pacific (SP) and integrated into the Texas & New Orleans (T&NO) Railroad, SP's operating railroad for Texas and Louisiana. H&TC's original route remains in active use through Navasota, today operated by Union Pacific (UP). In 1878, the newly chartered Central & Montgomery (C&M) Railway built 27 miles of track between Navasota and Montgomery to provide timber interests in Montgomery County with rail access via the H&TC line. In 1882, the Gulf, Colorado and Santa Fe (GC&SF) Railway initiated plans to build from their main line at Somerville to Conroe and points east to tap the growing east Texas timber industry. The Somerville to Navasota segment was built in 1883, and the C&M was acquired by Santa Fe to provide additional trackage toward Conroe which was reached in 1885. This line remains in service, now owned by Burlington Northern Santa Fe. In 1902, the International - Great Northern (I-GN) Railroad passed through Navasota as it constructed a main line from Houston to Ft. Worth. The I-GN would later come under the ownership of the Missouri Pacific (MoPac) Railroad. In Navasota, the I-GN paralleled the other two railroads through town with the Santa Fe line in the middle, the I-GN to the east and the H&TC to the west. The former I-GN route was abandoned north of Navasota by MoPac, but south of Navasota, the line remains in operation by UP. The postcard photo at right shows a "NAVASOTA" sign on an interlocking tower. The sign also shows the numeral "3", possibly reading "No. 3". Although there were eventually two towers in Navasota, the proximity of the railroad depot in the background makes this almost certainly the Santa Fe/Southern Pacific tower, designated Tower 41 in the Railroad Commission of Texas (RCT) management system on June 24, 1904. The meaning of the numeral "3" on the tower sign remains to be determined. The style of this tower is identical to many other towers that involved the Southern Pacific. Comparing Navasota Tower to Tower 16, Tower 17, Tower 21, Tower 30, Tower 81, Tower 100 and Tower 121, particularly note the band of small circular patterns between the upper and lower stories. Also, in most cases, the door frame incorporates a small window above the door. The other tower in Navasota was Tower 9. It was authorized for operation on June 16, 1903 at the crossing of the I-GN and the H&TC approximately 1,600 ft. northwest of Tower 41. In 1904, the I-GN constructed a branch line from Tower 9 to Madisonville; this line was abandoned in 1944. For 60 years, all three rail lines co-existed through downtown Navasota. In 1965, SP and MoPac agreed to share the H&TC line to College Station and abandon the I-GN line north of Tower 41. This eliminated the need for Tower 9. Today, Tower 41 has become an automated interlocking cabinet and the three lines still run parallel through town. The fate of the original Tower 41 and Tower 9 structures is unknown.

Historic Map, Navasota, 1925

Above: This index to the 1925 Sanborn Insurance Co. map of Navasota has been annotated to highlight
the railroads through town and the location of the two towers. Apparently, the draftsman did not fully
understand the names of the railroads. Along the left side of the image, he identifies two of the railroads
as "Gulf Coast & Santa Fe RR" and "International & Great Western RR"!

Historic Photo, Tower 9

Above: This photo, provided courtesy of the Denver Public Library Western History and Genealogy collection, was
taken by Robert W. Richardson. It pictures Texas & New Orleans locomotive #412 passing a signal tower in Navasota,
Texas on December 15, 1946. In the background, an interlocking tower is visible (see magnification below left). Based on
comparison to the "Navasota Tower" photo above and other information, it appears that the tower in the background
is Tower 9. Below right and further below are image magnifications showing that this train is at milepost (MP) 71.25.
Official T&NO sidetrack records posted at the T&NO Archives (file SideTrkRec1938_DAL_p012.pdf) state that Navasota
was officially located at MP 70.76, approximately one half mile south of this train's location. If MP 70.76 represents the
milepost of the joint GC&SF/H&TC passenger depot in Navasota visible in the postcard photo, then the location of the
train at MP 71.25 can be estimated as 0.49 miles north of the station. This would be approximately 1,000 ft. north
of Tower 9, which is consistent with the distance to the tower in the background of the photo.
 

 

Historic Maps, Navasota
 
Above: The 1925 Sanborn Fire Insurance map of Navasota shows Tower 41 located in central Navasota where the Santa Fe tracks (center tracks)
cross the H&TC tracks to the left that were parallel to the I-GN tracks to the right. Magnification (right) shows the building to be a 2-story
"RR Signal Ho" (House) with the stairs on the northeast side. Note also the proximity of the combined GC&SF/H&TC depot northwest of the tower.
The location of the stairs and the location of the depot match the postcard photo of "Navasota Tower".
Below: The same 1925 Sanborn map of Navasota shows Tower 9 located where the I-GN line to Ft. Worth crosses over the H&TC line. The
right-hand track is the I-GN line to Madisonville which will parallel the H&TC for some distance before veering off to the east. Magnification
(below right) shows Tower 9 to be a 2-story "Signal Tower" with an L-shaped staircase on the south side of the tower. This is consistent with the
magnified image of what we believe to be Tower 9; that image was taken facing south toward downtown so the staircase on the south side is not
visible but downtown buildings are visible in the background. Note also that the absence of large buildings on the Sanborn map in the vicinity of
Tower 9 is explained by the fact that the map was made 21 years before the photo was taken.
 

The conclusion is that the tower in the background of Robert Richardson's photo is Tower 9, based on the following observations:
1. The tower number on the side appears to be a single digit.
2. In comparison to the "Navasota Tower" photo, this tower lacks the band of circular patterns between the windows and the
    lower structure, the roof line and chimney appear different, and the surrounding ground is different.
3. The background buildings and the lack of a visible staircase match the Sanborn map detail.
4. The location of Tower 9 with respect to milepost 71.25 is consistent with its appearance in the background of this photo.

R.J. writes about Interlocker 41:

"This crossing, especially in the direction we are going [on the Santa Fe], and with a train going off on the old I&GN like the one in the picture, can be a bit disconcerting at night when you are tired and approaching it. On more than one occasion I have approached this crossing with it having a green aspect on our signal, slowing for the 10 MPH restriction over it. Suddenly I hear a horn blowing repeatedly for the crossing in town, a bright headlight comes around the curve, bearing down on us at 25 MPH. One begins to second guess the green indication we have, then the train suddenly curves off to your right and passes by! Had it proceeded on the old SP, it would have crossed our path, and that is what runs through your mind at the moment."
