Texas Railroad History - Tower 56 - McGregor

A Crossing of the Gulf, Colorado & Santa Fe Railway and the St. Louis Southwestern Railway

 

Left: Documentation produced by the Railroad Commission of Texas (RCT) shows that the Tower 56 interlocking plant became operational on October 22, 1904 serving the Gulf, Colorado & Santa Fe (GC&SF) Railway and the St. Louis Southwestern (SSW, "Cotton Belt") Railway. The tower was integrated into the Union Depot built at the same time. Common for manned towers in Texas, its number is visibly presented as a white placard on the tower siding. The number and character of passenger stations that preceded Union Depot during the prior two decades of rail service is undetermined.

Santa Fe Depots: Gulf, Colorado & Santa Fe Railway by Robert E. Pounds and William W. Childers ((c) 2012, The Santa Fe Railway Historical & Modeling Society, Inc.) The book describes the photo...

"Photographer K. B. King was aboard the southbound Texas Chief, Train 15, as it pulled away from McGregor, Texas on July 1, 1951. Built in 1904, this joint depot with the Cotton Belt was constructed with an interlocking tower which controlled the crossing in the background. ... Although missing its tower, the McGregor depot stands today as the Amtrak station for Waco and the surrounding area..."

Left: The Union Depot with Tower 56 at McGregor looks symmetrical, but it's not. Count the eave braces; the Cotton Belt side (right) was shorter than the Santa Fe side. The depot was in the southwest quadrant of the crossing (undated photo from DeGolyer Library, Southern Methodist University, hat tip, Myron Malone.)

The Gulf, Colorado & Santa Fe (GC&SF) Railway was founded because Galveston's leaders wanted to have a second railroad off the Island, preferably one that did not pass through Houston (for reasons best explained elsewhere.) To effect its plan, the GC&SF built its own bridge over Galveston Bay to Virginia Point and proceeded northwest, ostensibly heading for Colorado but on a path that remained well south of Houston. Tracks reached Brenham in April, 1880 and Caldwell in early July. On January 14, 1881, tracks entered the railroad's Temple Junction construction camp (named for GC&SF Chief Engineer Bernard Temple) eight miles east of Belton. It was considered a "junction" because the GC&SF had chosen the camp to be the departure point for construction of its Northern Branch, a branch line cited in its Texas railroad charter. As the population in the vicinity of the camp grew, the Post Office decided that the name would simply be Temple.

GC&SF service out of Galveston was extended to Belton on March 18, 1881, and the "main line" beyond Belton continued northwest toward Colorado with tracks laid to Lampasas in 1882. As track-laying entered this vast area where there was plenty of livestock but little population, progress slowed. A branch line to San Angelo opened in 1888, but otherwise, the end of the "main line" was stuck at Coleman for more than twenty years. GC&SF management attention focused elsewhere; the real main line would be the Northern Branch.

Left: Norton's Union Intelligencer (Dallas) in its March 20, 1880 edition carried this note about the efforts of Waco's citizens, led by Dr. Gregor C. McGregor, to convince the GC&SF to build the Northern Branch through Waco. At this date, the GC&SF had not even reached Brenham, but its charter requirement for a Northern Branch was well known. Waco was doing its best to get an early advantage in seeking the GC&SF tracks. Much to the chagrin of Waco residents, the Northern Branch passed twenty miles to the west.

Consistent with geography and reputation, Fort Worth rather than Dallas was viewed as the future rail gateway to the West, matching the GC&SF's West-focused philosophy (e.g. Colorado, Santa Fe in its name.) To build from Temple to Fort Worth, the GC&SF avoided the soon-to-be hotly contested Waco market by opting to route via Cleburne. Waco was already served by the Houston & Texas Central Railway whereas Cleburne had no rail service at all. Its population had tripled in the 1870s and efforts to build a Cleburne - Dallas rail line were already underway.

When rail baron Jay Gould was elected President of the Missouri, Kansas & Texas ("Katy") Railway in late 1879, the industry quickly surmised Gould's intention to build south from the Katy's Red River bridge (near Denison) to Laredo via Fort Worth and Waco. The GC&SF was a small railroad with limited capital; it did not want to battle Gould in the Waco - Fort Worth market. From Temple, a line through Cleburne was the better choice. It was shorter, and with no direct competition, the GC&SF would have its pick of right-of-way.


Left: Prior to its tracks reaching Temple Junction, the GC&SF commenced construction on the Northern Branch. Existing rail service made Fort Worth a good logistics base for construction equipment and materials. The effort began with contracts for grading from Fort Worth south to Cleburne awarded on November 19, 1880. (La Grange Journal, November 24, 1880)

Right: The GC&SF did not wait long to begin northward construction from Temple. The
Brenham Daily Banner of May 18, 1881 reported on plans to sell lots at the new towns of Moody and Banks. Moody still exists 14 miles north of Temple, but Banks dissolved when the town of McGregor was founded. GC&SF service to Fort Worth began in January, 1882.

Left: The Galveston Daily News of September 11, 1880 quoting the Waco Examiner reported on Dr. McGregor's efforts to guide another line, "the narrow-gauge" railroad, into Waco. The Examiner also speculated dismissively about a report that the GC&SF would bypass Waco.

In 1880, the Texas & St. Louis (T&SL) Railway was laying narrow gauge tracks from Tyler to Waco with plans to continue into the ranch lands farther west. The company had been founded as the Tyler Tap Railroad in 1871 to bring rail service to Tyler by "tapping" the Texas & Pacific (T&P) Railway at Big Sandy. In 1879, the name was changed to T&SL as a 107-mile segment was built from Big Sandy to Texarkana, continuing into Arkansas and Missouri toward St. Louis. In January, 1881, the T&SL claimed the marketing name Cotton Belt Route, but it was still called "the Narrow Gauge" by many newspapers though there were other narrow gauge railroads in Texas (it was converted to standard gauge c.1887.) Though financial reorganizations ensued, ultimately becoming the St. Louis Southwestern (SSW or SLSW) Railway, it always remained the Cotton Belt. Dr. McGregor, champion of Waco rail service, monitored its progress and undoubtedly helped in arranging right-of-way, depot grounds, etc. By the spring of 1881, the Cotton Belt was in Waco skirmishing with Gould's construction forces over rights-of-way. Gould had leased the Katy to his Missouri Pacific (MP) railroad and was marching southward through Texas under the MP banner. MP didn't have a Texas railroad charter, so Gould assigned track ownership to the Katy (which, as it turns out, also lacked a Texas railroad charter! But that's another story...) Long before the Cotton Belt bridged the Brazos River at Waco in April, 1882, its surveyors had plotted the route westward to Gatesville, a town that had promised a $30,000 bonus for rail service. The route crossed the GC&SF near Banks where the new town of McGregor Springs was founded in honor of Dr. McGregor.


Above: The
Galveston Daily News of September 4, 1881 reported that the "the Narrow Gauge" crossing point of the GC&SF had been determined. It would become known as McGregor Springs, in honor of Dr. McGregor.

(Fort Worth Daily Democrat, June 15, 1882)

Far Right
: The
Galveston Daily News of August 20, 1882 announced the public sale of town lots at McGregor Springs.
 

Right: This excerpt from a lengthy article published in the McGregor Mirror of July 19, 1940 mentions the town moving "back from the Springs to its present location" as the reason "Springs" was dropped from the town name. The word 'back' is a geographic reference, not a time reference; the word 'away' would have been a better choice. The springs were along Harris Creek a quarter mile north of the railroad crossing, hence easily accessible land was available in greater quantity south of the crossing, farther from the creek and springs, and the town naturally grew in that direction. But the story implies that this growth occurred over many years to cause the name transition to "McGregor". Newspapers tell a different story. If it was ever used, "Springs" was dropped quickly by the railroads in public timetables and advertisements. Only two months after the sale of town lots, ads in the Galveston Daily News of November 18, 1882 show the GC&SF (below left) and the Cotton Belt (below right) had already begun identifying the town as "McGregor."
           
As early as mid October, 1882, only six weeks after the sale of town lots, property deed registrations for McLennan County were using "McGregor" as the location. The Post Office at Banks was relocated that same month, but whether it ever used the name "McGregor Springs" is undetermined.

In the summer of 1882 as the Cotton Belt was building through McGregor to Gatesville, the focus of GC&SF management was elsewhere. They were seriously considering the Chicago, Texas & Mexican Central (CT&MC) for acquisition. The CT&MC was the railroad that had finally completed a line between Cleburne and Dallas. It was having financial difficulties, and the GC&SF wanted to serve Dallas, which was more populous than Fort Worth. Construction of the Dallas - Cleburne line had been overpromised and poorly delivered, but its inevitable completion as a branch to Dallas formed part of the rationale for building the Northern Branch through Cleburne. It was time to act, so the GC&SF made the purchase on August 1, 1882. Gaining Dallas as a service market was a strategic move that unfortunately did nothing to solve the GC&SF's biggest problem -- it was entirely dependent on local traffic. Unless the GC&SF could find a partner to stimulate traffic from out-of-state markets, it was destined to become subservient to the bigger railroads in Texas: Southern Pacific (SP) and the Gould companies (the Katy, the T&P, and the International & Great Northern, Texas' largest railroad.)

The obvious suitor for the GC&SF was the much larger Atchison, Topeka & Santa Fe (AT&SF, "Santa Fe") Railway which did not yet have a Texas presence. AT&SF viewed Galveston as an attractive port for agriculture exports from its base in the Plains States. The GC&SF's main line from Ft. Worth to Galveston would be a boon to AT&SF's network if the two railroads could establish an appropriate interchange point. Negotiations resulted in an 1886 agreement under which AT&SF would acquire the GC&SF on favorable terms if the GC&SF completed three construction projects within a year: 1) Ft. Worth north to Purcell, Indian Territory (Oklahoma) to meet AT&SF building southward; 2) Dallas to Paris to meet the St. Louis & San Francisco ("Frisco") Railway building south from Missouri, providing a gateway to the Midwest that was not controlled by Gould, unlike the Denison and Texarkana gateways; and 3) Cleburne to Weatherford to connect with the T&P, establishing a shortcut between Galveston and west Texas that bypassed Ft. Worth (although it involved Gould's T&P, the idea was that export freight to Galveston from the West would take this alternative route via Weatherford and Cleburne since the original GC&SF "main line" northwest from Belton was stuck at Coleman and would remain so for another 25 years. Santa Fe eventually built northwest from Coleman and crossed the T&P near Sweetwater in late 1910.) The GC&SF was able to lay 300 miles of track in one year to complete all of these projects, a substantial accomplishment by any measure. The acquisition proceeded as planned in 1887 and the GC&SF began operating as a wholly-owned subsidiary of AT&SF.

Left: The Railroad Commission of Texas (RCT) gained authority to regulate rail crossing safety in 1901. It promoted the use of interlocking plant technology leading to a flurry of RCT-approved installations. Plans for an interlocker at McGregor were reported by the Austin Statesman on April 5, 1904. In January, the Fort Worth Record and Register had reported that a new Union Depot was being planned for McGregor ..."something badly needed." During the depot planning phase, Santa Fe received approval to integrate the manned interlocking tower into the new depot. Tower 56 was commissioned for operation on October 22, 1904, but whether the Union Depot also opened at that time (or perhaps was already in use) has not been determined. Santa Fe had opened a union depot with an integrated interlocking tower three months earlier at Morgan, 44 miles north of McGregor. A decade later at Milano, Santa Fe built a union depot with an integrated interlocking tower to replace a depot and a stand-alone interlocking tower.

Whether Santa Fe was leading the initial design of the new McGregor Union Depot is undetermined, but once RCT permission was granted for Santa Fe to lead the construction project for the new tower, it is no surprise that an integrated tower with Santa Fe architectural stylings was incorporated into the depot design. RCT's list of active interlockers dated October 31, 1904 states that Tower 56 had opened nine days earlier with a 24-function electric interlocking plant. Rather than employing the manufacturer to install the plant, Santa Fe performed the installation itself, a relatively new approach for Santa Fe but something SP had done frequently. The GC&SF had conducted its first interlocking tower installation at Tower 50 in Morgan only three months earlier. The GC&SF had also installed interlocking plants at Wallis and Cameron within a day of the Morgan installation.

The 24 functions in the McGregor plant consumed the full capacity of the interlocking machine spread over eighteen working levers. A typical minimal manned interlocking required twelve functions, so the plant's higher function count implies that it controlled signals, switches and derails associated with sidings and connecting tracks between the two railroads. The McGregor crossing had existed long before 1901 when RCT began regulating crossing safety, hence the railroads were required (by RCT regulation) to pay equal shares of the capital cost of the tower and interlocking plant. The recurring costs for operation and maintenance were shared on the basis of each railroads' function assignments as a percentage of the interlocking plant's total function count. RCT documentation lists Santa Fe with the responsibility to staff the tower, and it undoubtedly took the corresponding lead for maintaining the tower and the plant. Santa Fe would bill the Cotton Belt periodically for its share of recurring labor, materials and utility costs.

                           
                   
Above: The first passage (upper) is extracted from a SSW corporate report reprinted in the Commercial & Financial Chronicle of September 30, 1911. It notes that as of April 10, 1911, the GC&SF had contracted to operate trains "over the rails of this company" (Cotton Belt) into Waco including use of the Cotton Belt freight and passenger depots at Waco. The lower graphic shows that passenger service to Waco appeared in a Santa Fe system-wide Public Timetable dated May 26, 1912. The extent of this service remains undetermined.

Left: This ad in the McGregor Mirror of January 13, 1928 shows service to Waco continued at least into 1928. The last nightly train arrived from Waco at 12:45 am and returned to Waco at 3:45 am. Either Santa Fe paid the Cotton Belt to haul this train, or Santa Fe kept a switcher at Waco during the day, perhaps to conduct freight operations between the two towns.

The Stephenville North and South (SN&S) Railway was chartered in 1907 to build 43 miles from Stephenville south to Hamilton. Hamilton was only 32 miles from Gatesville, so in 1910, the Cotton Belt bought the SN&S and extended its tracks to Gatesville, expanding Cotton Belt operations to Hamilton and Stephenville. A 32-mile extension west to Comanche was completed in 1912, departing the Hamilton - Stephenville tracks at Edson five miles north of Hamilton. At Comanche, the Cotton Belt connected with the Fort Worth & Rio Grande (FW&RG) Railway (which became a Santa Fe property in 1937.) This was the farthest west the Cotton Belt operated along this line.

The Cotton Belt tracks from McGregor to Gatesville took a 27-mile circuitous route to cover a straight line distance of only 19 miles. In part, this was to avoid multiple crossings of the Leon River (although two were needed) but it also facilitated service to Lime City where a lime production facility operated for many years beginning in the 1880s. Continuing west, the route veered south, apparently seeking easier terrain, but it also passed through Leon Junction where it made a sharp turn to the northwest to proceed into Gatesville. The Leon River was nearby, but there was no "junction" at Leon Junction. A rail line from Lampasas northward had been proposed, and enterprising landowners apparently pitched Leon Junction as the crossing point with the Cotton Belt. The Cotton Belt complied but the line from Lampasas was never built. The Cotton Belt tracks were laid decades before the development of the massive Fort Hood U.S. Army base which has a northern border nearly to Gatesville. At least one spur into the base was built off the Cotton Belt.

Southern Pacific (SP) acquired control of the Cotton Belt in the early 1930s. Though SP was in the process of merging its Texas and Louisiana lines under the Texas & New Orleans (T&NO) Railroad, the Cotton Belt was omitted from the consolidation. Shortly after the SP acquisition, the dismantling of the SN&S tracks beyond Hamilton began. By the end of 1934, the only track segment still officially owned by the SN&S was the line from Gatesville to Hamilton. It remained in service until 1942 and was then abandoned, the last vestige of the SN&S. Cotton Belt service continued to Gatesville for another thirty years. In 1972, the Cotton Belt tracks were abandoned west of Lime City.

The Bluebonnet Ordnance Plant opened in 1942 at McGregor to manufacture various munitions for the U.S. during World War II. The plant was served by both railroads. Production ceased in 1945 and the facility began producing solid rocket propellants. Over time, auxiliary facilities were built in the area for similar purposes, including rocket engine testing. One of the facilities has become the Rocket Development and Test Facility for SpaceX but it is no longer served by rail.

In 1972, the Cotton Belt tracks were abandoned beyond Lime City. It remained the end of the line until 1989 when SP service to McGregor and Lime City was terminated and the tracks were mostly abandoned between Atco (on the western outskirts of Waco) and Lime City. Some trackage remained in place near Tower 56 and was sold to Santa Fe so they could serve industries in McGregor that had been served by SP. The impetus for SP's curtailment of service west of Waco was the 1988 abandonment of the Cotton Belt tracks from Corsicana to Waco. Two other SP connections to Waco had already been dismantled (at Giddings c.1959, and at Bremond c.1965.) The Corsicana line had been the only remaining connection at Waco with SP's rail network. SP's tracks at Waco and the branch to Lime City became stranded.

Bradley Linda explains how SP continued operating its Cotton Belt lines in Waco. The key was trackage rights on MP, which had been acquired as a wholly-owned subsidiary by Union Pacific (UP) in 1982.

"After the Waco-Corsicana abandonment, SP built a 'freight connector' between the north end of the SSW yard and the former MP tracks near Orchard Lane. They ran the MP down to Valley Jct. then over to the SP yard in Hearne, and vice versa. In the 90's there was quite a lot of business on the East Waco - Atco segment, Warren Flour downtown, and a plastic flower pot place and Gulf States Paper between New Road and Valley Mills Dr. next to Franklin. Gross-Yowell Lumber got loads of lumber on the 'Westview team' next to McCoys. There was a diaper manufacturer, a beer distributor, and several other customers, but the big customer was the Lehigh White Cement Co. at Atco (formerly Atlas-Portland Cement.)"

In the early 1990s, SP began cleaning up its balance sheet in anticipation of financial consolidation in the railroad industry. One such step was to merge the Cotton Belt fully into SP, retiring the separate SSW corporation. The demise of the Cotton Belt nickname was unfortunate; it had represented an active railroad since 1881. In the mid-90s, UP acquired SP. This gave UP the Waco-area Cotton Belt tracks out to Atco, site of the cement plant (which UP still serves.) McGregor remains on the Santa Fe main line, now operated by Burlington Northern Santa Fe (BNSF) as a result of the mid-90s merger of AT&SF with Burlington Northern.

Conner, hat tip Mark Nerren) Above Right: This vintage postcard shows an eastbound Cotton Belt train stopped at McGregor (Steve Goen collection.) Maintaining the crossing diamond at McGregor was no longer required when the Cotton Belt line to Waco was severed. The Cotton Belt tracks that were sold to Santa Fe were converted to industrial leads accessed by connecting tracks from the Santa Fe main line. The east lead runs approximately 1.5 miles; the west lead runs about 0.5 miles. All tracks are now owned and operated by BNSF.

Employee timetables issued by the railroads soon thereafter do not give any indication that the interlocker was converted to an automatic plant, suggesting that it continued to be operated manually by depot staff.

Below
: This 1958 image ((c) historicaerials.com) shows that the primary interchange yard was behind the depot with multiple tracks. There was also a connecting track in the east quadrant across from the depot. Both connectors remain intact to service local businesses but recent ground imagery suggest that the tracks behind the depot are used infrequently.
