The order, signed in April but only recently announced, is the biggest single contract for WJIS and is also the manufacturer's first foray into the metro rolling stock market. Until now, the company has mainly specialised in automatic peoplemovers (APM) and LRVs.
According to WJIS, the new trains use a permanent magnet synchronous motor (PMSM) which saves up to 30% in energy consumption compared with induction motors.
Integrated real-time smart information systems will also be used on the Seoul Metro network for the first time to provide data related to maintenance and efficiency. Currently, the condition of rolling stock on the network has to be checked directly onsite.
The order comprises 200 vehicles for Line 5 and 136 cars for Line 7. The first trains will be delivered in August 2020 while the remainder of the order is due to be fulfilled by November 2022.
