Subway drivers provide working meals during work. Specifically, there are special lunch boxes and thermos cups in the cab of subway drivers, so drivers can eat during breaks or when stopping at transfer stations. These working meals are generally distributed by the subway company to ensure quality, hygiene and safety. In addition, Nanjing Metro will also carry out health checks on drivers and provide necessary medical security and health management services to ensure that they can complete their work tasks healthily and happily.
