You know, I just came back from visiting Nanjing not long ago; please refer to my previous writings of 重遊南京(一)-(六).  Pukou was one of the sights to see, though I didn't mention it in my article(s).    Pukou used to be the destination of Jingpu Railway, from which passengers and freights were ferrying across Yangtze River to the opposing city of Nanjing.  Why didn't the trains cross the river through bridges?  Because there was none of them.  But now it is said that there have had over a hundred bridges all over the long, wide Yangtze. 

The long deserted Pukou terminal is going to be refurbished, a report from World Journal said.  Please see the story at:  http://www.wj411.com/portal/index/newshare_weibo.jsp?id=1613917&source=13

P.S.  The report mentioned that famous essay "背影", for part of its storyline had been related to Pukou station.  Let's review the story and my translation at http://blog.udn.com/kkuo0810/7140108.
