Every day, two musicians bring joy, music, and positive messages to passengers riding the Trensurb train between Porto Alegre and Novo Hamburgo, in southern Brazil. In a space often filled with silence or stress, they create real human moments. To celebrate them, Guilherme, an admin assistant at a local school, will buy 2 new guitars and a portable speaker and gift them as a surprise whilst on the Trensurb train on his way to work.
