The story

from WikipediaRead it all ↗

The Alamosa, Colorado, post office opened on March 12, 1878, and the Town of Alamosa was incorporated on August 12, 1878. The town was established by the Denver and Rio Grande Railroad and quickly became an important rail center. Alamosa was the terminus of the D&RG until 1881, when the line was extended to Monte Vista. The railroad had an extensive construction, repair, and shipping facility in Alamosa for many years and headquartered its remaining narrow-gauge service here with trackage reaching many points throughout southwest Colorado and northern New Mexico. Alamosa County was created on March 8, 1913, with Alamosa as its first and only seat.
