Signalling
Line 10 is one of the first lines in China capable of automatic train operation. However, upon opening it was operated with drivers on board. In 2020, the line started transitioning into GoA4 unattended train operation with driver cabs being gradually removed for the entire Line 10 fleet.

Between December 2020 and January 2021, SATEE supplied its OptONIX and ONIX metro traction systems for 156 metro cars of Shanghai Line 10, with support from Xi'an Alstom Yongji Electric Equipment Co. Ltd (XAYEECO). It was also responsible for the train control monitoring system (TCMS) of Shanghai Line 10, and the line's train electrical design. During the same period, CASCO has successfully put into service its Urbalis 888 signalling solution on six of these metro lines in Chengdu and Shanghai.
