PVG to Huangshan via overnight train

My China Eastern flight SFO to PVG arrives at 17:20 on 10/10/2016. I want to take the overnight train to Huangshan that departs at 20:16 that same evening. I will only have carry on luggage (no checked luggage). Will I have enough time go through immigration and transfer to the railway station to catch the train? Thank you. Betty (California USA)
