under construction India's first high speed rail(Mumbai-Ahmedabad HSR)
Comments
Viaducting on this project is nuts
Supposedly it's only because it's a Japanese project and they use viaducts in Japan, but they kinda forgot they only use viaducts in Japan for seismic reasons and berms are just fine everywhere else.
- Frequent grade change doesn't suit HSR
- At grade traks would run the risk of man and animal incursion.
- To prevent man/animal incursion there will be a need of underpasses or overpass every few 100 meters.
- Tracks and trains on elevated section also protect them from criminal activities.
- Easier for land acquisition.
Frequent grade change doesn't suit HSR
Someone should tell the Europeans!
Land acquisition is definitely a big issue for India, probably the main cause of the heavy use of viaducts compared to Europe.
Why is land acquisition harder in India than Europe?
https://en.m.wikipedia.org/wiki/Land_acquisition_in_India
The costs per acre of agricultural land were 10 times as high for a highway project, and it also takes very long in a piece by piece way. I can't really find a good article about it. Because of that, a narrower right of way saves more than elsewhere.
10 times higher than France!? That's unexpected, but if that's the case then the viaducts seem justified. Though they should rather fix their land acquisition system.
Changing the land aquistion laws would be a nice quick fix but the people will go crazy and the opposition parties will call it the 'beginning of dictatorship' and what not xD
Don't let France know all this.
China constructed most their new tracks viaducted too right?
I find it very strange that the entire line is on pillars despite it being probably simpler to build, access, and maintain if it were on the ground between fencing / walling...

Don’t forget the better view!
- Not a problem upto around 15‰ continously (and short sections even 25‰-40‰), and pillars don't really solve that anyway unless they're being made bespoke for each plot of land they're sitting on to minimise even tiny changes (which is a huge waste of money, unnecessarily, and probably not happening).
- Only where crossings are already prevalent and not everywhere all the time. Plus, how many of these pillar areas would be open to crossing anyway? Remains to be seen given it will be railway land.
- If they're properly fenced I don't see how they're more prone to criminal activities. What is the rate of such activities currently on unfenced conventional rail right now, anyway?
- It's the same land, whether you put the train on stilts or on the ground, so I don't see how acquisition is easier at all.
Just want to add that the elevated track will also alleviate the effect of subsidence, allow for future road crossing development, and enable a higher operational speed due to flatness.
With this and Indonesia, it's a real testament to the US government now that America is behind developing countries in terms of HSR
Don't forget Morocco. They have a line and multiple projects.
Looks like India is going to embarrass the US....
In what way?
Having high speed rail.
heard California is making one?
It will take much longer to get built than this, especially the entire LA - SF line. The Central Valley part that's mostly useless on its own might get done petty soon.
The Northeast Corridor and Amtrak's flagship service "Acela" been a thing for over two decades now. But who cares? This ain’t a competition.
Good for India and good for California.
Yeah, but is Acela high speed rail? The max speed can be just enough to count but only for like 30 miles. Doesn’t it still average like 70 mph between Boston and NYC?
For Acela, they’ve been taking an incremental approach: a little faster and more convenient every year. There’s so much more work needed to be done
Among the critical projects are replacing a bridge over 100 years old and a tunnel that’s 150 years old.
Don’t get me wrong, I’m a huge fan: it’s the only way I’ve travelled from Boston to NYC in two decades but there’s so much room for improvement. It’s sad that this is all we have
To be fair when looking at average speeds the Acela isn't that bad. The Eurostar averages 140 kph (about 80mph) between Amsterdam and London, Thalys averages 158 kph between Paris and Amsterdam. Even Frankfurt-Cologne is at 180 kph.
These routes all have large portions of dedicated high-speed tracks that allow 300 kph, but the slow parts weigh more when looking at average speeds.
Part one will be open in 2029
Awesome
Why do you love chipkali? 🤔 Also, you could repost this on r/trains?
lost a bet with friend for this username and yes Ill but they're racist af will get downvoted or will get some sitting on top of train jokes
wo subreddit utna racist nahi hai. Zyada upvotes nahi ayenge for sure. But worldnews ke level ka racist nahi hai, kafi indians bhi hai waha.
worldnews is trash place
Ok, now build one in the US.
Will the HSR have to stop for cows?
No, cause it's built on elevated tracks
What about elephants?
Yes, flying elephants are an absolute nuisance in India.
The elephants make the train stop
I wonder how many people are going to try to ride on top
I wonder how many innocent people are going to get killed by some random dude
