The Texas South-Eastern Railroad Company was founded by T. L. L. Temple in 1900 in Diboll, Texas to serve Temple’s East Texas lumber operations. From 1900-1996, it was primarily used to transport forest products to and from the Diboll mill, connecting to the mainline St. Louis & Southwestern Railway in Lufkin. This collection consists of photographs depicting TSE’s locomotives, freight cars, employees, constructing track of the Lufkin Z&OO zoo railroad, and transporting Engine 22 to the Texas State Railroad, as well as business papers providing histories of TSE’s locomotives, the Pineywoods Special, and records from the company’s last year hauling freight from Diboll to Lufkin.
