What, among others, should be checked before you set about driving a double-carriage tram?

The tram driver's duty before starting a journey is to inspect the vehicle's technical condition. In the case of the two-carriage tram shown in the picture, one of the key components is the coupling connecting both carriages. Its correct technical condition is essential to ensure the integrity of the set and the safety of passengers, preventing the carriages from uncoupling during the journey.
