Buenos Aires Transport Network Operates With Trambus and Expanded Payment Options
The system of 137 colectivo lines, six Subte routes and urban trains moves residents daily after the November 2025 rollout of the electric Trambus service.
How we reported this
The Trambus, a fully electric service introduced in November 2025, now links northern and southern districts and cuts journey times by as much as 40 percent between those zones.
City records show the addition forms part of nine Metrobus corridors and 300 kilometres of protected bike lanes already in place. These elements sit alongside the colectivo network, which remains the dominant mode with its 137 lines running around the clock, although night frequencies drop after midnight and all rides require a SUBE card.
Subte and Train Schedules Shape Daily Movement
The Subte runs on six lines labelled A through E plus H, opening at 5:00 on weekdays and closing at 23:00, while weekend hours run from 8:00 to 22:00. Credit, debit and virtual wallets can now be used at turnstiles, a change listed on the official tourism site. Urban trains link the city centre with the Gran Buenos Aires area, carrying more than one million passengers each day and operating from 5:00 until 1:00.
Traffic Volume and Commute Lengths Remain Steady
Average daily vehicle counts on main avenues reach 11,600, while the typical public-transport journey lasts 79 minutes and nearly one-quarter of users spend more than two hours travelling each day. These figures come from municipal mobility reports and underscore why the Trambus reduction in north-south travel times matters for regular riders.
Passengers can verify current SUBE balances and contactless options before boarding any of the five transit modes that include colectivos, trains, the Subte, light rail and ferries.
