How did the railroad change New Mexico's economy?

people that weren't Mexican also tried to settle on Mexican land.

Railroads have a place in New Mexico's history. When the railroad arrived from the north it immediately took up rapid transport of goods and passengers such as had previously come in along the Santa Fe Trail, fueling new prosperity and growth in the Territory.

Hope this helps!
