The AusRAIL 2025 railway exhibition, held over 3 days from November 26 in Melbourne, Australia, has been successfully concluded. Kleines Wunderland created a diorama depicting Hyundai Rotem's hydrogen-powered society and collaborated by managing and operating it at the Hyundai Rotem booth. For this exhibition, we designed and incorporated Australia's iconic landmarks — the Opera House and Harbour Bridge — adding a touch of Australian beauty to the display. We are grateful to have received tremendous interest and appreciation from local visitors at AusRAIL 2025.
