A Crossing of the Texas & New Orleans Railroad and the Southern Pine Lumber Company
The Houston East & West Texas (HE&WT) Railway began building a narrow gauge line north out of Houston in 1877, eventually reaching Nacogdoches in 1882 and the Louisiana state line in 1885. Unfortunately, the HE&WT was built as a narrow gauge railroad which limited opportunities for exchanging traffic. The HE&WT overcame this mistake by converting the entire line from Houston to Shreveport to standard gauge on 29 July 1894. Five years later, Southern Pacific (SP) bought the HE&WT but continued to operate it under that name. In 1927, the HE&WT was leased to the Texas & New Orleans (T&NO) Railroad, SP's principal operating subsidiary in Texas and Louisiana. In 1934, the HE&WT was fully merged into the T&NO.
One of the major towns on the HE&WT was Lufkin, the county seat of Angelina. Twelve miles south of Lufkin, the community of Diboll was founded in 1894 when Thomas L. L. Temple built a sawmill adjacent to the the HE&WT. He named his new concern the Southern Pine Lumber Company (SPLC). The company grew substantially over many years and, with mergers, acquisitions and buyouts, became one of the largest wood products companies in the U.S. The mill in Diboll remains active today.
In 1900, T. L. L. Temple chartered the Texas Southeastern (TSE) Railroad to expand rail service in and out of the SPLC mill in Diboll, with aspirations to serve other mills in east Texas. One of the first TSE projects was to convert an existing SPLC narrow gauge logging line to standard gauge. The line ran a short distance east from the mill at Diboll, crossing the HE&WT in the middle of town. TSE extended this line 15 miles northeast to a connection with the Cotton Belt railroad near Homer, east of Lufkin, at a location named Diboll Junction. At the time, the Cotton Belt was independent of SP, so TSE's connection to the Cotton Belt provided competition for the HE&WT for outbound wood products from the mill at Diboll. TSE expanded west from Diboll and added lines elsewhere in east Texas, eventually operating more than 50 miles of track. TSE hauled logs to mills, but also served sawmills by carrying outbound wood products and providing passenger and mixed freight service.
In the 1920s, TSE operations changed. TSE began to focus on other aspects of the lumber business and Southern Pine Lumber Co. locomotives began hauling SPLC's raw logs directly to the Diboll mill (using TSE's tracks where available.) In 1920, 98% of TSE's freight tonnage came from hauling wood products, and 67% of this was logs. By the end of the decade, wood products was down to 85% of TSE's freight tonnage, and 75% of this was lumber coming out of the mills.
In 1939, the Cotton Belt line out of Lufkin through Diboll Junction and east to Prestridge was abandoned. It is likely that TSE operations between Diboll and Diboll Junction had already ceased, but we have no confirmation of that. Once the line to Diboll Junction was out of service, most likely by the late 1920's or early 1930s, the TSE crossing of the HE&WT was no longer needed because the forest east of Diboll was apparently no longer being logged. According to "old-timers" in the Diboll area, sometime in the early 1940s, SPLC decided to reopen logging areas east of Diboll which required them to reestablish the former crossing of the HE&WT (now T&NO). Unlike prior operations, the crossing was now deemed to require an interlocker, which was assigned by the Railroad Commission of Texas (RCT) as Tower 185 and placed in service on 22 September 1941 (per documentation provided by Carl Codney.) This crossing was short-lived; Tower 185 was dismantled in 1944. [We list a decommissioning date of 27 March 1944, but the specific reference for this date has been lost!]
The T&NO line continues to see heavy traffic through Diboll, now owned by Union Pacific (UP), and UP serves the mill through a spur on the south side of Diboll. It is apparent from satellite imagery that the mill continues to make extensive use of locomotives and railcars.

Annotated Map of Diboll
This annotated 1963 USGS Topo map of Diboll shows the Southern Pine Lumber Co. mill located slightly west of the
T&NO main line, in red. All other railroad tracks on the map belong to SPLC; locomotives were used extensively in
bringing logs to the mill and moving them through the milling process. The dashed blue line shows where an extension
of a mill track crossed the T&NO main line at Tower 185 and continued northeast to Diboll Jct. on the Cotton Belt.

Above: Looking south, the UP tracks are at left proceeding south in the distance through the center of Diboll. At right, the former SPLC spur that crossed the T&NO
at Tower 185 terminates but remains intact.
Below: Looking north, the utility poles align with the former SPLC track and proceed across the UP tracks. The pole at far right is part of this alignment which demonstrates
the former SPLC right-of-way through the site of Tower 185. The interlocker, presumably a cabin, would have been visible from this vantage point in the early 1940s.
