Signalmen giving the "advance" signal on Calçada da Estrela. Exact location unknown, but possibly at the corner of Calçada da Estrela and Rua de São Bento, as the streets behind the photographer are narrow and only one-way traffic is possible.
In 2024 tram route 28 headed to Estrela would come from behind the photographer and go up the Calçada da Estrela visible in the photo. Trams going the opposite way would make a right turn to the left of the photographer onto Rua de São Bento. When Carris took over this route the route from Estrela was rebuilt thus eliminating the need of signaling at this location.
