Texas Railroad History - Tower 146 - Edcouch

A Crossing of the Southern Pacific and Missouri Pacific railroads in the Rio Grande Valley


Above: Sometime in the 1930s or early 1940s, John W. Barriger III took this photo while visiting the Rio Grande Valley of Texas. The photo was almost certainly taken in Edcouch, based on the following evidence. First, the cabin visible in the distance matches the scene and appearance of the only confirmed photo of Tower 146 (below) that has been obtained. Second, based on other photos in Barriger's sequence, he was known to be in the Rio Grande Valley, but this scene does not match any of the other cabin interlockers in that area. The position of the tracks and the semaphore signals with respect to the cabin is consistent with a north view along the Missouri Pacific (MP) tracks in Edcouch. Barriger's private car was pulled by an MP train, so he is likely stopped at the depot south of the crossing and has left his private car to take the photo as he is clearly not on the tracks.


Above LeftThis is a magnification of the photo above right, but it's the best confirmed image we have of the Tower 146 cabin interlocker in Edcouch. Two semaphores are visible which guarded the Southern Pacific (SP) line immediately south of the cabin. The normal position for the semaphores was down for the MP line and up for the SP line. Above Right: Seen in this photo is the depot and tin-covered freight house with the "EDCOUCH" sign and the familiar MP brown-and-cream painted doors. The Tower 146 cabin is visible in the distance, as is the 1958 black and white Ford of the station agent, Mr. Rufus Milligan. This would date the photo to between 1958 and 1968, when the MP line was abandoned. The view is from the southwest corner of the freight house looking along the east side of MP's main track to the north.

In 1904, the San Antonio & Aransas Pass (SA&AP) railroad sought to extend its rails to the Rio Grande Valley of Texas. The impetus likely came from SA&AP's previous owner Southern Pacific (SP) wishing to compete with a new rail line to the Valley being built by the St. Louis, Brownsville & Mexico (SLB&M) Railway. The SA&AP was divested from SP ownership by court order in 1903, but SA&AP proceeded with plans to build to the Valley from their nearest service point, the town of Alice. In 1904, the first 36 miles was completed from Alice south to Falfurrias. The Valley was less than 80 miles away, but construction stopped and was not restarted until the SA&AP was re-acquired by SP in 1925. SP's main line to the Valley was completed in 1927 from San Antonio to McAllen, passing through Skidmore, Alice and Falfurrias among many other south Texas towns. Also that year, a 63-mile branch line from Edinburg to Brownsville was built. These lines provided SP with traffic from a vast area of agriculture and expanding population.

The Valley was already served by the Missouri Pacific (MP) railroad which had acquired the SLB&M in 1925. MP constructed branch lines into the area around Edinburg in 1926, and a year later, SP's branch line to Brownsville crossed the MP at Edcouch, a new town named for....Ed Couch! Ed was a local banker and landowner (and, apparently, a self-promoter!) who foresaw the advantage of having a town midway between Edinburg and Harlingen served by two railroads. Unfortunately for Ed, the town never really prospered despite the railroad crossing.

A cabin interlocker protecting the SLB&M/SA&AP crossing was approved for operation by the Railroad Commission of Texas (RCT) on February 5, 1929, identified as Tower 146. RCT's annual list of interlockers first mentions Tower 146 as "Under Constr." in a table published December 31, 1928, a few weeks before it was commissioned. RCT listed the location of Tower 146 as "Ed Couch". The list published at the end of 1929 gave the final commissioning date and described the interlocker as a mechanical cabin with eleven functions, still identified as being at "Ed Couch". This spelling was retained on RCT's final comprehensive list published at the end of 1930. Consistent with RCT's policy, the subsidiary companies were listed as the two railroads protected by the interlocker rather than listing the parent companies MP and SP. The SA&AP ceased to exist in 1934 when it was merged into the Texas & New Orleans (T&NO) Railroad, SP's primary operating company for Texas and Louisiana. The SLB&M officially disappeared when it was merged into MP in 1956.


Above Left: This is the original, unedited photo showing the cotton gin across the tracks. Above Right: An additional photo taken at the same time is a view of three boxcars waiting to be loaded. Note that the Frisco boxcar has wood sides and all three have friction bearings. This was a typical view of an old south Texas town in the 50s, full of dust and grime and very, very tired. There is a gravel road crossing with a couple of kids seen next to a packing house. When the train came to pick up these cars, the track would creak and groan under the weight, and the wheels would crush the gravel and weeds which accumulated over the railheads. An old Missouri Pacific GP7 with faded blue and white colors would huff and belch smoke, and the train crew would open the interlocker to set the way for their return to Monte Alto, Hargill and Raymondville.

Above Left: This view is of a Gulf Oil Corporation facility of some sort. The boxcar is probably just spotted there for storage. Note that the track is almost buried in the sand and gravel which comprised most of these hot little towns in the Valley. Above Right: An old, faded switch stands in the heat of the setting sun (shadow shown on the east side of the marker). The sun has even parched the weeds during this hot, dry summer. My grandfather had a chemical business in an old railroad building just to the right of this switch stand. It was a typical tin-covered affair with MP brown-and-cream doors and peeling paint. (photos and captions provided by Bill Bentsen)

Observations by Bill Bentsen:
My grandparents lived in Edcouch in the lower Rio Grande Valley, at the crossing of the MP (SLB&M) and the SP (SA&AP), site of Tower 146. The SLB&M line was a north-south line, while the SA&AP line was east-west, and the lines crossed at a 90-degree diamond. The interlocker was a cabin-type where the train crews operated the controls. The cabin, located at the northwest corner of the crossing, was approximately 15 feet square and was on short stilts to ensure that any flooding from tropical hurricanes would not damage the interlocking plant or building. The construction was entirely of wood with clapboard siding, and the roof was asphalt-type shingles, probably black. There were double-hung windows across the south side (SP side) and east side (MP side) to assure a good view of the crossing. The cabin was painted white at one time, but the effects of time and weather had pretty much rendered the paint job dull gray by the time I was observing it. There were two signs on the interlocker, one on the MP side and one on the SP side. The signs read simply "146". The entry to the interlocker was from the MP side via a short stairway with wood handrails that led to a wood door. The stairway was accessed over a very short wood sidewalk/bridge which crossed the ROW drainage ditch alongside the MP track. There were Armstrong-type handles inside which controlled the semaphores and the derails via standard interlocking pipes and rollers. The pipes that controlled the SP line ran along the north side of the SP track, while the pipes that controlled the MP track ran along the west side of the MP track. The interlocker was the most simple type as it was only used to protect the routing by setting the semaphores and derails properly. The SP line (which was used substantially more) had a clear indication with the semaphores in the upright position and the derails closed while the MP line was always set in the stop or semaphore down position with the derails open. I do not recall that the semaphores were lighted; however, they well may have been.

The interlocker was used only by the MP crew. As I recall, when the train arrived from Raymondville via Hargill and Monte Alto (southward), it would stop at the closed semaphore and wait until the brakeman went to the interlocker. He opened a standard railroad switch lock which protected the building, then he moved the Armstrong levers until the MP line was cleared over the SP line. The mechanism changed the semaphores and derails appropriately. Once this maneuver was accomplished, the MP train would cross the SP line in complete safety as intended. The signal apparatus was left in this position until after the switching was completed and the train crossed back northward. Once it cleared the crossing and the caboose was completely past the north signal, the brakeman reversed the setup and again set the signals for the SP line. He then locked up the cabin and boarded the caboose to leave town.

The location of the original SA&AP Edcouch depot was on the northeast corner of the diamond. I never saw the depot as it was removed long before my knowledge of the area; however, the foundation remained as witness to the depot's existence. Passenger service on the SP ended shortly after WWII according to my mother, and the depot was razed shortly after that. The MP station was southeast of the diamond, and was a wooden building with a freight house attached. It was painted the standard MP brown and cream and it had a bay window facing the track. Interestingly, MP never offered passenger service on this line, but the freight agent at the station could issue passenger tickets. MP passenger service was available on the mainline from Harlingen to Houston, and the closest passenger station to Edcouch was at Raymondville. This was where we always boarded the train when we went home to Dallas after visiting my grandparents. The station was severely damaged by a hurricane in the mid-60s, and the railroad elected to abandon it rather than repair it. The agent retired simultaneously.

MP abandoned the Edcouch to Weslaco 7.56-mile line in 1961, and then abandoned the Monte Alto to Edcouch line in 1968. This, of course, was the end of the need for the interlocker, which was abandoned in 1968 also. The SP line continued to operate under SP ownership until the merger with Union Pacific (UP). In 1999, UP filed to abandon the "Santa Rosa Industrial Lead" between Edinburg and Rogerslacy, and the final rails were removed from Edcouch in 2000.

[Not to be outdone by Ed Couch, Rogerslacy was named for...  Rogers Lacy!]

Left: SP used an internal form known as a "D-205" to document interlocker functions for purposes of determining how expenses would be shared with participating railroads. This one for Tower 146 was drafted on August 1, 1928 based on an interlocking plant design dated March 19, 1928. The document notes that SLB&M is responsible for maintenance, and that SLB&M's train crews will operate the interlocker, i.e. the signals will always be lined to allow SA&AP trains to pass unless an SLB&M train is actively using the crossing (which makes SLB&M crews responsible for re-lining the signals after crossing so that SA&AP trains have a clear signal.) The REMARKS column confirms RCT records that the plant was placed in service on February 5, 1929. Another notation states that as of April 1, 1947, T&NO (SP) train crews took over maintenance responsibility.

Subsequent iterations of this document show that the design plan was revised on January 21, 1949 to reflect removal of the derails on SP's tracks. The next revision was made on April 1, 1952 to add two signals of unspecified functionality. This caused the agreed expense allocation to become 50/50. Two later revisions are documented, beginning on February 1, 1955 for "...account inoperative approach signals on the St.LB&M Ry." The final revision was made on September 1, 1959 for "...account T&NO spur track removed from interlocker." This final version also notes "Out of service Sept. 17, 1968".

Above: (With SP in blue and MP in pink) SP's main line from Falfurrias came in at the top of the map, crossed the MP at Tower 149, and continued south through Edinburg to McAllen. SP's branch to Harlingen crossed existing MP tracks in Edinburg (Tower 145) and Edcouch. All of these track segments have been abandoned except a short segment of the former SP line west of Tower 145 and a branch coming north on the former SP line from McAllen to Edinburg operated by the Rio Valley Switching Co.


Above: While the rights-of-way for the rail lines in Edcouch are at least vaguely apparent in Google Earth satellite imagery, that is not the case on the ground, at least from Google Street View imagery. Other than railroad-related street names (yellow ovals), there is very little physical evidence that any railroad ever passed through Edcouch, let alone two of them.
