With most residents not allowed to leave their homes and restrictions tightening in parts of China's most populous city, commuters early on Sunday needed strong reasons to travel, Reuters reported.
Shanghai's lockdown and curbs in other cities have battered consumption, industrial output and other sectors of the Chinese economy in recent months, prompting pledges of support from policymakers.
Many who ventured out in the commercial hub wore blue protective gowns and face shields. Inside the carriages, passengers were seen keeping some empty seats between themselves. Crowds were small.
Four of the 20 lines reopened, and 273 bus routes. Some had closed in late March, others later, although sporadic service continued with a limited number of stops.
The city of 25 million expects to lift its city-wide lockdown and return to more normal life from June 1. Most restrictions on movement will remain in place this month.
Shanghai's 800-km metro system averaged 7.7 million rides a day in 2020, according to the latest data, with an annual passenger throughput of 2.8 billion.
Trains will run 20 minutes apart for limited hours. Commuters must scan their body temperature at the entrance and show negative results of PCR tests taken within 48 hours.
Shanghai has gradually reopened convenience stores and wholesale markets and allowed more people to walk out of their homes, with community transmissions largely eliminated.
Still, parts of the city have recently tightened curbs, underlying the difficulty of resuming normal life under China's zero-COVID policy, which is increasingly at odds with the rest of the world.
