Shanghai Metro Line 14 has been in the final sprint phase since the early morning of September 28, after obtaining signal safety certification and starting no-load running map test on August 27, 2021.

Shanghai Metro Line 14 is the first high-density, high-capacity, fully automated driverless line of the Shentong Metro Group with 8-segment A-type trains.

As the brain and core system of the metro’s running command, the signalling system deployed on Line 14 is a fully automatic operation one based on the TSTCBTC® 2.0 product developed by Thales SEC Transport (TST), which is designed for high reliability and availability to meet the highest level of automated operation of GoA4.

As Line 14 is a downtown line with a very high forecasted passenger flow, to improve the line’s overall capacity, TST has also solved the key problem affecting the capacity improvement, namely the turn-back capacity, by carrying out a series of design optimizations of the signalling system to fully exploit the potential of it and existing equipment.

At present, TST has been able to achieve a turn-back capacity of 120 seconds or less for 8-segment trains, which lays a solid foundation for subsequent operations and organization adjustments and is fully prepared for increasing capacity.
