The correct answer is B) connected Texas to New Mexico and Arizona to California.
Early train routes connected Texas to New Mexico and Arizona to California.
That is why it was so important that the Pacific Railroad Act of 1862 authorized the Construction of the Transcontinental Train that connected the East of the US with the Pacific West. That piece of legislation authorized the Central Pacific ad the Union Pacific companies the construction of this important railroad to improve trade and transportation across the country. The construction ended in Promontory, Utah. on May 10, 1869.
