Lerdo continued projects initiated by Juarez, most visibly the construction of railways. He opened the first railway line in Mexico from the port of Veracruz to the capital Mexico City, which was begun by Juárez and Lerdo inaugurated in January 1873. However, Lerdo had seemingly contradictory policies about railway construction. He was concerned about U.S. encroachment in northern Mexico and resisted construction of railways to the border. He is quoted as saying, "Between strength and weakness, the desert," meaning the weakness of Mexico vis-à-vis the U.S. and the desert as a useful barrier. After a delay, he attempted to have a Mexican company construct the north-south line to the U.S. border, but the effort failed. Ultimately, he did approve a proposal of U.S. railway entrepreneur Edward Lee Plumb to build the line. Mexican supporters of construction thought Lerdo had delayed too long and botched the chance of Mexicans building the line, while Lerdo's opponents viewed him as caving to the U.S.
