A Crossing of the Fort Worth & Denver South Plains Railway and the Panhandle & Northern Texas Railway
In 1928, the Ft. Worth and Denver City (FW&DC) completed a branch line between Silverton and Lubbock under the charter of the FW&DSP which had embarked on a strategy of gaining access to agricultural business in the South Plains area. They had previously built a branch line under this same charter from the FW&DC main line at Estelline to Quitaque, and this line was extended to Dimmitt in 1928. The FW&DSP line into Lubbock crossed the P&NT at Tower 141, which was commissioned as a 7-function automatic interlocker and placed in service on February 12, 1931. This was a significant interlocker in Texas history because it was the first automatic interlocker installed in Texas. The Railroad Commission of Texas jointly authorized automatic interlockers for two FW&DSP crossings of the P&NT, one in Lubbock and one in Plainview. The Lubbock interlocker was installed first, and got the lower tower number. The rationale for automatic interlockers and the process of gaining Commission approval is presented in more detail on the Plainview (Tower 142) webpage.
As shown in the Google Earth image below, an overpass on M. L. K. Jr. Boulevard now passes over the former crossing. The diamond has been removed, but connecting tracks are in use for various purposes in all directions from the former crossing. All of the lines are now owned by Burlington Northern Santa Fe Railway.
