We exhibited a futuristic hydrogen mobility city diorama featuring Hyundai Rotem's trains, hydrogen trams, and charging infrastructure at AMXPO (Asia Machinery & Manufacturing Expo) 2025, held from September 23 to 26 at KINTEX, Goyang. This diorama was first exhibited at InnoTrans 2024 in Berlin last year, and was showcased domestically this year at BEXCO in Busan and KINTEX. As the first diorama in Korea to feature trains, trams, and cars operating via automated control, we are grateful to have received tremendous interest and appreciation at AMXPO as well.
