Signalmen changing the signal at the end of Calçada do Combro.
Exact location unknown, but possibly near the corner of Calçada do Combro and Rua do Poço dos Negros. The street behind the photographer (Rua dos Polais de São Bento) is too narrow for two way traffic.
In 2024 this route it taken by tram 28 going towards Estrela, while the opposite direction was diverted onto Rua do Poço des Negros when Carris took over this line to eliminate the need of signals.
