The Martin Lake Line is a railroad owned and operated by Texas Utilities and hauled Lignite coal from nearby mines at the Oak Hill Mine and Beckville Mine, until their closures in the later 2010's, to the Martin Lake Power Plant and has a connection with the BNSF Railway's Longview Subdivision near Tatum, TX. Coal from the Powder River Basin in Wyoming is transferred onto the line via the connection with BNSF. The line was constructed as an electrified line, using 25 kV AC, 60 Hz electrification, and operated GE E25Bs and former Ferrocarriles Nacionales de México GE E60s;[1][2] however, the line was de-electrified in 2011.[3]
