This seems like the few places in China where they have parallel high speed rail lines linking the same cities. Others I can think of is Beijing to Tianjin and Guangzhou to Shenzhen.
Nanjing to Shanghai hsr line has more stops,with top speed 300km/h,curve radius 5500m,larger ultrahigh and less super high fit for running at 300km/h,stations are all in the city centre.Beijing shanghai line is diffent,with top speed 380km/h,curve radius 7000~12000m,larger ultrahigh and less super high fit for running at350km/h,stations are little far from the city centre .The old line is full of freight trains. there are 215 locomotives with power of 9600kw in nanjing and 115 9600kw locomotives in shanghai.

Shanghai-Nanjing intercity stops at the Shanghai Rail Station right in the city center, while Shangai-Beijing starts at Shanghai Hongqiao Station slightly west of the city center. Also the intercity rail also serves as the Shanghai-Nanjing portion of Shanghai–Wuhan–Chengdu High-Speed Railway. If there is no parallel high speed rail lines, there would be a choke point in the Shanghai-Nanjing section.

I've always wondered, what are these concrete protrusions next to the tracks? (circled in red)I don't see them on HSR in other countries.

Strange comment there of max. operating speed 160km/hr.
Then it is not an existing high speed railway and should not be a continuous blue line. It either is a high speed railway yet to open in 2014 - a dashed blue line then - or else it is a slow speed railway, and should not be on the map at all.
It's not on the map above..

I was just about to ask if they build this line for cargo, because Fangchenggang is the port city of Guangxi, but apparently, they already have parallel conventional line which could be used for cargo, so how can this be feasible if they have only 1 train a day..

their function is to fix the position of the track plate.There are 4 kinds of unballasted track.this kind is from Germany,called Boegl plate,is widely used in 300+km/h hsr.Boegl plate has Superior performance,but is difficult to produce,and so expensive.So after 2010,a new kind of track plate replaced the Boegl plate.

Thank you very much! Nice to have the mystery solved.

What are they using instead now(after 2010). It looks like they've used this form almost everywhere in China on HSR bridges:

The 4 kinds are CRTS ⅠⅡⅢ,these three kind are all prefabricated.and the last kind called double-block unballasted track.CRTS Ⅰis from Japan,cheap and easy-made.Whuhan to Guangzhou hsr is the first line using CRTSⅠ.Chinese find out it is not as good as CRTS Ⅱ(the boegl plate) in normal condition,So then all 300+km/h line begin to use CRTSⅡ.BUT CRTS Ⅰfit for high-latitude area,so Harbin to Dalian,Lanzhou to Urumchi using this kind.double-block are using in tunnels,they are cast-in-place.so at
the time 2010 ,after Comprehensive consideration of the advantage and disadvantage of all the unballasted track,China push out CRTSⅢ.Chengdu to Dujiangyan line is the first time experiment of CRTSⅢ,then Wuhan to Xianning,Shenyang to Dandong,Panjin to Yingkou begin to use CRTSⅢ

Just took a ride on the new HSR line from Liuzhou to Guilin. Was very comfortable, scenic and only took 1 hour reaching a top speed of 200km/h. Here's a short video I took.

I agree that as a railway infrastructure, it is amazing. However, the video is ruined by that watermarks!

"Completed in Zhejiang province"? Are there any tracks left to lay in the Jiangxi province part between Nanchang and Zhejiang province border, or is that part already completed at some earlier time?
