DONG XUMING/FOR CHINA DAILY

Technicians inspect an electric multiple unit train on Tuesday at Ningbo EMU train operations depot, built by China Railway No 4 Engineering Group Co Ltd, in Zhejiang province. Covering a construction area of 60,000 square meters with 17 individual buildings, it manages parking, maintenance and overhaul of high-speed trains, and is dubbed a "land aircraft carrier", becoming the first such depot traversing the 100-meter-wide Houtang River in the Yangtze River Delta region.
