International & Great Northern (I&GN) Railroad
• Completed its line from San Antonio to Laredo, added Galveston access, and built a main line from Houston to Fort Worth.
• Dominated Texas railroads for years and was acquired by Jay Gould in 1880, briefly lost, and reacquired in 1891; his son George led it for 25 years.
• Emerged from receivership in 1922 as the International–Great Northern (I-GN) Railroad.
• Acquired by Missouri Pacific (MP) in 1925 and later by Union Pacific (UP) in 1982; merged into UP in 1997.
• Most lines remain active under UP, except the abandoned Fort Worth route.
San Antonio & Aransas Pass (SA&AP) Line
• Became part of Southern Pacific (SP) in 1925.
• SP abandoned the line from Giddings through Rockdale to Cameron in 1959, Decommission Tower 54.
Rockdale, Sandow & Southern (RS&S) Railroad
• Originated as a six-mile mine spur built by Federal Fuel Co. in 1919.
• Became a common carrier in 1924 to support lignite shipments; sought ICC approval for interstate rate authority but was denied due to regulatory precedent from Tap Line Cases.
• Continued local service until lignite use declined, ending in 1950.
Rebirth for Aluminum Transport
• In 1952, Alcoa built a smelter near the mine and upgraded RS&S for shipping aluminum and ores.
• ICC approved interstate rate authority due to expanded operations.
• The Rockdale smelter became the world’s largest but was shut down in 2008 due to pollution issues.
Present Status
• Alcoa sold the land in 2021 to developers; plans for a massive industrial complex were announced in 2023.
• RS&S tracks remain intact but out of service.
