TINA trams' air conditioning sparks debate amid summer heatwaves

Passengers have raised concerns about the air conditioning in the new TINA trams during recent warm weather. Some have questioned whether the systems are working effectively. Stadtwerke Halle has confirmed that all units are fully operational and performing as designed. The air conditioning in TINA trams is engineered to handle frequent door openings at stops while maintaining energy efficiency. Unlike cars, trams must allow warm air inside when doors open, which affects cabin temperature. Once the doors close, the system runs at full power and can lower the indoor temperature by 2°C compared to outside conditions.

STADLER, the manufacturer, is remotely monitoring the systems in real time during trial operations. There are no automatic shut-off thresholds for temperature, ensuring continuous cooling and dehumidification. The goal is to keep the passenger area noticeably cooler than the outside air, not to achieve extremely low temperatures.

Compared to older MGT6D and MGTK models, the TINA trams' air conditioning proves more effective, particularly in high heat. The system prevents overheating by constantly circulating cooled and dehumidified air through ceiling vents. The air conditioning in TINA trams is functioning as intended, with no reported faults. It cools the cabin effectively despite frequent stops and door openings. Passengers can expect a consistently cooler environment than outside, though not an extreme chill.
