Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Last I looked (years ago) Shanghai was supposed to get a RER-type system (with R1, R2,... lines) with the extension and re-designation of choice metro lines (see here for example), apparently the plans were shelved?

UrbanRail.Net > Asia > China > SHANGHAI Subway - Metro

Metro Line 9 (Shensong Line) was conceived as a regional express line (R4), to run from Xu Jia Hui on Line 1 towards the southwest to Song Jiang New City, but it has eventually been developed as a full metro line across the city centre. When it opened in Dec 2007, it was not yet connected to any other metro line.
