The lecture evening last Wednesday, 6 March 2024, on the topic of “Technology of the bogies of the new trams (TINA ST15) of heag mobilo” was once again well attended. The presentation by the former Managing Director of heag mobilo, Karl-Heinz Holub, met with great interest, not least because it was a topic with a strong connection to Darmstadt. There were also regular reports in the local press in the run-up to the introduction of the new tram type.
