📋 Tender Overview
One year after the launch of the Buho buses, almost 34,000 passengers benefited from their operation in the metropolitan area. In this period, the service accumulates 159,719 validations and 13,860 services performed, figures that show the growing use of lines B1, B2, B3 and B4 by workers, students and citizens who need to travel outside conventional hours. The Owl Network is part of the strategy promoted by the Vice Ministry of Transportation to expand the hourly coverage of public transportation, strengthen nighttime connectivity and provide a safe and predictable alternative. The service began operating in February 2025, in the period from 10:00 p.m. to 3:30 a.m., also incorporating National Police agents on board to reinforce passenger security. The night service has four lines defined based on a technical analysis of priority corridors and mobility patterns: B1 connects Asuncion with San Lorenzo, B2 connects with Limpio, B3 goes to Nemby and B4 to Luque.
