Southern Pacific Railroad of Mexico
Open-knowledge reference entry
The Southern Pacific Railroad of Mexico (reporting mark SPM) was a railroad subsidiary of the Southern Pacific Railroad in Mexico, operating from Nogales, Sonora, to Mazatlán, Sinaloa. The Sonora Railway was constructed by the Atchison, Topeka and Santa Fe Railway between 1879 and 1882, along with the connecting New Mexico and Arizona Railroad from Nogales, Arizona to Fairbank and Benson, Arizona. In 1898 the Santa Fe leased the line to the Southern Pacific in return for the latter railroad's line from Needles to Mojave, California. This arrangement continued until December 1911, when the Southern Pacific purchased both the Sonora Railway and the New Mexico and Arizona. The following June, the Sonora Railway became part of the Southern Pacific Railroad in Mexico.
The main line ran 1,095 miles from the Sonoran town of Nogales, just across the border from Arizona, to the city of Guadalajara, stopping at several northwestern cities and port towns along the way. Owned by the Southern Pacific Company, which operated a highly profitable railroad system north of the border, the SP de Mex transported millions of passengers as well as millions of tons of freight over the years, both within Mexico and across its northern border. Daniel Lewis (2007) reports it rarely turned a profit, and contends that SP executives, urged on by the media of the day, operated with a reflexive imperialism that kept the company committed to the railroad long after it ceased to make business sense.
It was sold to the Mexican government in 1951, becoming the Ferrocarril del Pacifico.
Southern Pacific abandoned the former New Mexico and Arizona Railroad section by 1960.
This brief starts where responsible research should: with the source description of “Southern Pacific Railroad of Mexico” as open-knowledge reference entry. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as open-knowledge reference entry. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 26, 2026. The linked authority identifier is Q7570287. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1879, 1882, 1898 and 1911.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
