Companhia Nacional de Caminhos de Ferro ao Sul do Tejo

Companhia Nacional de Caminhos de Ferro ao Sul do Tejo was a 19th-century Portuguese railway company established to develop transportation infrastructure on the south bank of the Tagus River. The enterprise played a significant role in the historical integration of the Barreiro region into the national rail network before its assets were absorbed into the state-controlled Comboios de Portugal system.
