冲高试验 is a test article of all HSRs. The speed in this test is the highest posssible speed. It is far higher than Max speed which is higher than normal operational speed.

Here is a CCTV report of CR380 reaching 486.1 kmph in the test.

So we have three figures:
  1. Operational speed, 400kmph for CR450. In all operational lines, this would be the regular top speed.
  2. Max speed, 450kmph for CR450. This is the top speed that the track, signal can tolerate. So it is still an operational speed that is within the regulation. But it wouldn't be used to plan the time table.
  3. Absolute Max speed, 600kmph for CR450, 486.1 kmph for CR380. These are like speed before a supercar driver felt loosing control or engine is sounding weird. They are only ment for knowing the upper limit, but never allowed to operate with passengers.



This route is track and wheel, not related to maglev.

Sounds like CR450 intends to break the 574.8kph record set by TGV in 2007, if not the 603kph set by Japan's maglev in 2015.

That station was built in 2006 and was intended to serve conventional green/red/blue trains only. I have more questions than answers. If the Shanghai South Railway Station already has enough empty platforms to serve new HSR EMUs, why did they build a whole new massive HSR station in Songjiang District right across the street from the Songjiang South Railway Station on the Shanghai-Hangzhou HSR? Isn't the Shanghai South Railway Station much closer to the city center and financial district? As built, the South Railway Station has 11 platforms, which is smaller than most post-2010 HSR stations, but bigger than older standard station (usually 7-9 platforms with 11-13 tracks total). I wonder if the Songjiang station was necessary given its size and distance from Shanghai city centre. Songjiang District is already being served by multiple metro lines, the old Songjiang Railway Station and the HSR Songjiang South Railway Station.

To reach those speeds, 400 kph, you need not only the locomotives and trains designed for that speed but extremely straight track with as few curved sections as possible. I would guess some lines have already been built to accommodate the higher speed. Otherwise you need tilting trains to traverse the curved sections at speed.

Right now maglev in China is still under development. Something like the Transrapid to Pudong Airport in Shanghai does not IMHO offer enough advantages vs conventional high speed rail. China is however researching higher speed maglev which should put maglev back in the race. Even Transrapid was supposed to be able to cruise at 550 kph. Although the implementation at Pudong is much slower. In part because of the relatively short track.

A lot of the high speed track for 350 km/h service were designed to accommodate speeds up to 380 km/h, e.g. Beijing-Shanghai line.

China Europe freight rail completed 19,000 train trips in 2024, up 10 percent year on year. Transporting over 2 million TEUs of cargo, up 9 percent year on year. Launched in 2011 as a flagship program under the China-proposed Belt and Road Initiative, the service now reaches 227 cities across 25 European countries and connects over 100 cities in 11 Asian countries.

A CETROVO 1.0 metro train leaves a parking lot before its operation in Qingdao, east China's Shandong Province, Jan. 10, 2025. The CETROVO 1.0 subway car started its operation on the Qingdao Metro Line 1 on Friday.

With a carbon fiber composite body and frame, it is lighter and more energy-efficient than the traditional subway train. (All photos by Xinhua/Li Ziheng)

this is pretty cool. They are making metro train with carbon fiber that can go 140km/h. a lot faster than your traditional subway.
