The Red Búho (Owl Network) night transport service is successfully strengthening mobility in the metropolitan area of Asunción, having recorded a total of 135,395 passenger validations to date. This figure reflects the growing reliance on the Asunción night bus network service in Paraguay’s capital since its launch.
Currently, the network operates four key routes that connect the capital with the surrounding cities of San Lorenzo, Limpio, Ñemby, and Luque. The buses run between 22:00 and 03:30, providing a crucial service outside of standard transport hours.
Ensuring passenger safety
To ensure passenger safety and peace of mind, agents from the National Police accompany the bus units on their routes. This measure provides greater security and protection for all travellers.
The routes themselves were not chosen at random. Instead, their itineraries were designed following a comprehensive technical analysis which identified priority corridors and mapped the real demand for travel during night hours. Consequently, the service offers a safe and reliable transport alternative for workers, students, and families moving through the metropolitan area late at night.
Breakdown of passenger demand
Analysis of early 2026 data shows a clear preference for one of the primary routes. The B1 line, which serves San Lorenzo, accounts for the vast majority of journeys with 102,296 validations. Following this, the B3 service to Ñemby has registered 18,710 validations. The B4 line connecting to Luque has seen 9,168 validations, while the B2 service to Limpio has recorded 5,221 validations.
