Line 2 train from downtown eastbound requires transfer to 4-car train to complete journey to Pudong Airport. In afternoon rush hour, the smaller train filled quite rapidly, and I hopped on at the last minute while others seemed to prefer waiting for the next train with seats available. Not as glamourous as the Maglev express, but the local transfer requires only crossing a platform, rather than exiting through gates and re-entering.
