quantitative
Five Shanghai Metro lines run without a driver or attendant on board at GoA4, the highest grade of automation: Line 10, the Pujiang line, and lines 18, 15 and 14, the last of which opened at the end of December 2021
clm-a110005705385d8e
quantitative
Line 10 opened in 2010 as one of the first lines in China capable of automatic train operation and carried drivers on board anyway; the switch to unattended running began in 2020, with the driver cabs taken out of the fleet
clm-de1da376b7ab0719
quantitative
The signalling comes from Chinese joint ventures of European suppliers — Casco, an Alstom and CRSC venture, on Line 10, and Thales SEC Transport, a Thales and Shanghai Electric venture, on Line 14
clm-1ea361260f77fbf2
quantitative
A 2011 collision on Line 10 injured 271 people after a signalling failure had forced a switch to manual operation
clm-fc9e8fcefb22160b
quantitative
Shanghai Metro reported 167 km of driverless GoA4 route across five lines when Line 14 opened at the end of December 2021, and said that made Shanghai first in the world for driverless metro scale
clm-1826fa587c348262
quantitative
trade press covering the same opening puts the five fully automated lines at a combined 167 km, inside a network that had just reached 831 route-km with 20 lines and 508 stations
clm-6d842d2a7568c23c
quantitative
Line 14 itself ran late: the signalling contractor announced in January 2018 that it was scheduled to enter service at the end of 2020
clm-5bae2b72e4d37d14
quantitative
It opened in April 2010 as one of the first lines in China capable of automatic train operation and ran with drivers for a decade; the cabs came out from 2020
clm-59e9a2e1dba28624
quantitative
on 27 September 2011, a signalling failure put the line onto manual working and one train ran into another that had stopped between Yuyuan Garden and Laoximen: 271 people treated in hospital, twenty of them seriously hurt, nobody killed

descriptive
No source here connects that to the ten-year wait for unattended operation, and it would be easy to assume one — but the sequence is worth holding onto, because the only figure the operator offers for the interval is a kilometre count
This layer records what is known about each source, what is still missing, and the exact snapshot this page is rendering. A missing date, archive or hash stays visible as missing.
Awaiting operator and domain-expert review; publication of this revision implies neither.
Erratum on this revision's envelope. The snapshot, its hash and its permanent link are untouched.

src-26e40a1c9b225fdeChinese state media relaying Shanghai Metro's own figures: five automated lines, 167 km, and the operator's claim of ranking first worldwide for driverless scale. Source of the impact figure; operator-attributed, not independently audited.
src-de415bc332243f17Established trade press, January 2022. Independent confirmation of the five fully automated lines and their combined length.
