If you’re a frequent user of the Sarmiento Line, start preparing a Plan B for getting around during the upcoming long weekend in July, because Trenes Argentinos has confirmed that service between Once and Moreno stations will be completely suspended for four consecutive days due to construction.
The massive service disruption begins on Thursday, July 9, and runs through Sunday, July 12, inclusive. The timing is no coincidence: it takes advantage of the Independence Day holiday and the bridge holiday.
Here’s everything you need to know so the service interruption doesn’t catch you by surprise and you can plan your days accordingly.
Why is the Sarmiento train service suspended during the July 9 holiday?
Instead of implementing partial or nighttime service suspensions that would drag out the work for months, Trenes Argentinos decided to carry out an intensive 96-hour shutdown to perform maintenance at various points along the Sarmiento Line.
The work includes track renewal, signaling improvements, and construction at underpasses. Here’s what you need to know:
- Caballito: track changes and the García Lorca Street underpass.
- Liniers and Villa Luro: Comprehensive modernization of the signaling system and work on the Irigoyen Street underpass.
- Ramos Mejía: Resumption and progress of construction work on the central platform.
- Morón: Structural improvements on Platform 2
- Castelar / Paso del Rey: Replacement of signaling wiring
- Moreno: Maintenance and Optimization Work
Full train service between Once and Moreno will resume as usual starting with the first train on Monday, July 13.

Guide to Travel Alternatives: How to Get Around Section by Section
The alternatives combine the subway, regular buses, and express highway services. We’ve put together this breakdown based on your route so you can choose the option that works best for you:
1. Options within Buenos Aires City and the surrounding area (Once to Liniers)
If you’re traveling between the first few stations, the subway and buses will be your main options:
- Subway Line A + Line 2: You can take Subway Line A to the San Pedrito terminal station and, from the transfer point at the intersection of Avenida Rivadavia and Nazca, transfer to the Line 2 bus.
- Line 8: It serves as a direct alternative for traveling along the corridor.
- Line 132 + Line 136: You have the option of taking the 132 to Primera Junta and transferring to Line 136, or making a direct transfer using Subway Line A and the 136.
- Lines 71 and 106: Another option is to take Line 71 to the Ángel Gallardo and Mario Bravo area to transfer to Line 106.
2. Service from Ciudadela to Morón
- Main lines (1, 88, 96, and 163): These lines will operate as direct replacements, covering various sections of the Sarmiento Line’s usual route.
- Line 166 (Haedo Branch): This becomes a key alternative thanks to its Gaona branch line via Haedo.
3. Express Services to the West: Castelar to Moreno
Local lines (336 and 392): Both companies will continue to operate on their usual routes to ensure short trips between stations on this final stretch.
Line 302 (Express via the Highway): This is one of the best options for long, direct trips, avoiding the intermediate stops on the avenues.
Line 57 (Atlántida): You can choose the 57 R Express service or use its strategic connections, such as the 57 Q/P branch in conjunction with Line 303, or the routes that connect with Lines 269 and 443.
