Which transportation development significantly impacted trade in New Mexico during the early 20th century?

The development of railroads was a pivotal factor in transforming trade in New Mexico during the early 20th century. Railroads provided a reliable and efficient means of transporting goods to and from the state, which opened up new markets for both local producers and consumers. They allowed for the quicker movement of agricultural products, minerals, and manufactured goods, significantly boosting the economy.

Before railroads, trade relied heavily on slower methods like horse-drawn wagons and less extensive road systems, which limited the volume and speed of goods movement. With the expansion of the railroad network, New Mexico became better connected to other parts of the United States, facilitating interstate commerce and encouraging investment in various industries. This not only helped local economies grow but also contributed to overall development in the region, making railroads a cornerstone of New Mexico's trade infrastructure during this era.
