The North Western operated triweekly passenger-train service in both directions between Salto and Quarahim.
[3] It served stations at Salto, Las Vinas, San Antonio, Stapevi, Palomas, Arapey, Santa Ana, Isla Cabellos, Zanja Honda, Santa Rosa, and Port Cuareim.
[4] Less than a year after its founding, Railway News reported on June 16, 1883, that the company directors, in their report for the ten months during which they had held office, stated that, owing to the publication of an unfounded telegram arguing that a revolution had broken out in Uruguay, only £88,115 out of the £340,000 debentures for which they asked subscriptions were placed.
The directors resolved to clear off, as far as possible, the liabilities which they had taken over from the North Western Railway of Monte Video Company, to put the existing line in good working order, and to proceed with the extension as far as Isla Cabellos (a station from which a large increase of traffic was expected), and, having thus given proofs to the Uruguayan Government that the company intended faithfully to carry out their agreement with them, to ask them to grant an extension of time for completing the railway to Santa Rosa.
Regarding the works upon the existing line, the railway superintendent reported that they are in good shape, and that an entirely new station, with the necessary goods and sheds was built at the Port of Salto, to take the place of the old terminus, which was inconveniently situated about 2 km (1 mi) inland.
