What line do I transfer from the Metro 2 @ Shanghai Guanglan Road?

Ill be coming in to PVG and taking the Line 2 into the center, but it says you need to transfer the metro Guanglan Road to a 8 car train. Will that train be labeled Line 2 or something different.

And will they announce the stops over the intercom system on the metro? I'm worried Ill miss the transfer stop.
