Buenos Aires Transport Officials Highlight 336 Bus Lines, Seven Subte Routes
City experts and planners describe the reach of 336 bus lines plus seven Subte routes as central to daily movement while noting recent contactless options and Metrobus gains.
How we reported this
Buenos Aires maintains 336 bus lines, seven Subte lines, seven train lines and nine Metrobus corridors, with all services payable by SUBE card or contactless Visa and MasterCard payments.
The system operates under ongoing fare reviews that began with an 8.4 to 11.1 percent bus increase and a subway fare of 1,336 Argentine pesos as of February 2026, according to records from the city tourism portal. Officials note these adjustments occur alongside monthly inflation-linked updates and separate toll rises of 9 to 10 percent on highways and Paseo del Bajo from the same month.
Peak Period Pressures on Specific Routes
Rush hours run from 7:30 to 9:30 AM and 5:30 to 8:00 PM, when Lines B and D plus Retiro-bound trains carry the heaviest loads. Transport planners cite these corridors as the points where frequency reductions at night on 24-hour bus services still leave gaps for essential workers.
Subte trains follow set schedules of 5:30 AM to 11:30 PM on weekdays, 6:00 AM to midnight on Saturdays and 8:00 AM to 10:00 PM on Sundays, data listed on the official tourism site. Experts at the city government level have pointed to these fixed windows when discussing how the network serves both residents and visitors without major timetable overhauls in the current year.
Metrobus Performance Metrics
The Metrobus BRT corridors have cut average bus travel times by 30 minutes while handling up to 250,000 passengers each day, figures recorded in project evaluations. Officials responsible for sustainable transport programs describe these corridors as a direct response to earlier congestion on mixed-traffic routes.
Contactless payments rolled out in January 2025 now sit alongside the SUBE system, giving riders two options on every colectivo and Subte station. Planners from the transport authority have stated that the dual-payment setup reduces boarding delays at busy stops across the nine corridors.
Commuters can review current fares and service alerts through the SUBE app or station displays before boarding, a step recommended by city transport offices to avoid delays during the established rush windows.
