1,200 Workers Convert a Train Station into a Subway in 3.5 hours
Watch 1200 workers race against time to convert an above ground train station to a subway line. The engineers only have 3.5 hours between 1:00am and 4:30am to complete this incredible feat.
Japan's Daikanyama St. station is Tokyo's fourth busiest platform so the construction has to be done after hours.
