May is a very important month in Argentina every year ; it is the month of the revolution. To celebrate, on Saturday, May 16, 2026, after midnight, you can ride for free on the historic wooden cars known as “Las Brujas” on Line A, as they will once again run free of charge between Perú and Acoyte . You can sign up starting May 13 at 12 p.m. Here’s how to sign up to enjoy a very special subway ride during May Week.
What are Las Brujas of Subway Line A and why are they a Buenos Aires icon
The “Las Brujas” cars date back to 1913, and their unique name comes from the fact that they belonged to the Belgian company Brugeoise et Nivelles. Until 2013, you could ride these unique wooden cars on Line A—which was also the first subway line in South America—until they were retired and replaced with new cars. Those who used to ride the “Las Brujas” every day through Buenos Aires know that, every time they return to the tracks, it’s a journey worth taking.
The “Las Brujas” on Line A are also part of Buenos Aires’ Cultural Heritage, and if you’ve never seen them, they still feature their original woodwork, period lamps, and leather seats. It’s like being in a moving museum.
This May Week 2026, you can enjoy touring Buenos Aires in the most beautiful subway cars in the world. The “Las Brujas” ride on Line A takes place on May 16 at midnight and is completely free, but requires prior registration.
Registration for the three different time slots opens on May 13 at 12 p.m. Spots are going fast!
Important: To sign up, you must be of legal age, and you may bring one guest. So, if you want to ride the “Las Brujas” with a child, the adult must be the one to sign up.
