Otis Continues Massive Modernization Project at Chongqing Metro

Line 2 work with Chongqing Rail Transit (CRT) nears completion without disrupting routine train service.

Otis China has nearly completed a first-of-its-kind project in the country to modernize 120 elevators and escalators throughout 18 train stations – all without disrupting routine train service. It’s the largest modernization project for Otis China and an important part of the urban renewal of Chongqing, a busy city with more than four million daily riders in the metro system.

Chongqing Metro is a unique rail network serving a densely populated and mountainous city, with multiple river valleys. Line 2 is 31.4 kilometers long, with elevated and underground sections and 25 stations. Opened in 2005, Chongqing Metro was the first urban rail transit line in western China and the first straddle monorail line in China. Line 2 remains one of the busiest monorail lines in the world, carrying a total of more than 1 billion passengers to date.

“We are proud to support Chongqing Metro over the years as it grows as part of the city’s ongoing urbanization,” said Otis China President and Chief Customer Product Officer Perry Zheng. “Otis offers advanced technologies and collaborates with customers across China to build and support smarter infrastructure that enhances efficiency and enriches the passenger experience.”

The year-long renewal and renovation project of Line 2 includes the legacy truss modernization of 95 escalators and the replacement and upgrade of six 515NPE escalators, two SPAN freight elevators and 16 Gen2® elevators. The escalators will now feature the Otis ONE™ IoT digital platform, which reinforces safety while supplying data that offers valuable insights for unit management and maintenance.

The complex topography and geography of Chongqing has made this modernization project very challenging. With a comprehensive project plan and a strong specialist team, Otis has worked closely with the Chongqing Metro team to carry out the massive transformation and, in parallel, maintain daily service operations. With the legacy truss modernization solution offered by Otis, the new escalators have been assembled in the factory and delivered to be installed directly on site.
