Wolmi Sea Train
monorail on the island of Wolmido in Incheon, South Korea
The Wolmi Sea Train (월미바다열차), formerly known as Wolmi Galaxy Rail, is a monorail on the island of Wolmido in Incheon, South Korea. The monorail line has 4 stations and covers 6.1 km connecting Wolmido Island to Incheon Station, the west terminus of Seoul Subway Line 1 and the Suin–Bundang Line. 1.15 km is double-tracked, but the loop around Wolmido (3.94 km) is single-track. Phase 2, if built, would have added 2 km single track connecting to Dong-Incheon station, also on Metro Line 1, with a potential Phase 3 looping back to Incheon station. The system is the first in the world to use Urbanaut technology, whose selling point is an inverse T-shaped track: large wheels run on the horizontal part of the track, while small wheels press against the rail and keep it in place.
The project was started in 2007, where it was originally designed to be a major monorail carrying 70 passengers. The line was scheduled to open in March 2010, but opening was repeatedly postponed. The project has a poor safety record. In April 2010, a test vehicle collided with a rail inspection vehicle, causing it to crash into a station, parts of which collapsed onto the street below. In August 2010, a wheel falling from the vehicle on a test run injured a pedestrian.
This brief starts where responsible research should: with the source description of “Wolmi Sea Train” as monorail on the island of Wolmido in Incheon, South Korea. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as monorail on the island of Wolmido in Incheon, South Korea. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Feb 18, 2026. The linked authority identifier is Q485362. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2007 and 2010.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
