In late January 2026 Ulsan city officials were set to decide whether to continue or halt the $3.8 bn hydrogen‑electric tram line (Line 1) that would run 10.85 km with 15 stations and open in 2029. Mayor Kim Sang‑wook chaired an emergency meeting, reviewing the legal and financial fallout of a suspension, including the non‑terminable contracts with Hyundai Rotem and Hansin Gongyeong, and floated a bus‑rapid‑transit alternative.

By the end of March 2026 the mayor announced that the project will proceed, citing legal advice that termination is not lawful. Detailed design work is slated to finish by March 2025, and construction will move ahead under the same consortium.
