The Texas State Railroad is not only a "Texas Treasure," it is the official Railroad of Texas.
The Texas state prison system established the railroad in 1881. Inmates built the line, which was used to transport hardwood which was used as fuel for the furnaces at the prison-operated iron smelter at the Rusk Penitentiary. The furnace supplied the State of Texas with iron products, including the columns and dome structure for the capitol building in Austin. The original construction was a narrow gauge line but was later built in standard gauge in order to join into the main line.
