Working in Suzhou – Living in Shanghai

Hi – I will be starting work in Suzhou next year and my wife will be working in Pudong (just over the river). Following our info trip we have decided that we want to live in Shanghai (on Metro Line2) so that she can be closer to the kids.

Does anyone have experience in daily travel to/from Suzhou? Don’t really want to use personal car (for economic and environmental reasons). The train looks ok but not ideal – what other options are there?

Thanks,
