NEW DELHI: A passenger train set a new national speed record of 160 kilometres an hour (100 miles an hour) on Thursday during a test between New Delhi and Agra.

The introduction of high-speed links and bullet trains were one of the key poll campaign promises of Prime Minister Narendra Modi, who won elections in May.

Today's test, part of the government's plans to upgrade the ageing rail network, saw the train complete the 200 kilometres between New Delhi and Agra in around 90 minutes. The top speed clocked at 10 kilometres more than the previous record.

But 160Kmph is not new as far as Railways go in India and definitely not "Bullet-train" level speeds.
160 Kmph trials were conducted on the treacherous Konkan Railway section back in 2002 and the trials were successful.

Indian Railways budget makes the case for change
08 Jul 2014





INDIA: Presenting his first budget since the new government took office, Railways Minister D V Sadanand Gowda said on July 8 that he wanted to see Indian Railways become ‘the largest freight carrier in the world’, having recently ‘achieved the distinction of entering the select club’ carrying more than one billion tonnes of freight per year, along with railways in China, Russia and the USA.

He recognised much needed to be done in terms of reform and restructuring, as well as putting IR’s finances in order. He admitted that IR had been ‘tight-rope walking’ in order to balance its twin conflicting objectives to ‘earn like a commercial enterprise but serve like a welfare organisation’. He wants to see more investment concentrated on technical improvements and capacity enhancements on the main corridors, rather than being ‘frittered away’ on populist new lines serving rural areas that generate little traffic.

Structural reform will clearly take time, and despite the expectations of rapid change engendered by Prime Minister Narendra Modi’s election success the 2014-15 railway budget is not very different from its predecessors.

IR’s gross traffic receipts for 2013-14 grew by 12·8% to a record Rs1 395bn, but this was Rs9bn below target, while operating expenses were Rs5bn above budget at Rs976bn. IR’s operating ratio deteriorated by 2·7 to 93·5, and capital expenditure was Rs594 below plan.

The 2014-15 budget projects a 4·9% increase in freight traffic to 1 101 million tonnes, with earnings estimated at Rs1 058bn. With passenger traffic expected to remain constant, passenger income will rise to Rs446bn thanks to fare increases announced on June 25. Total expenditure is projected to rise by Rs151bn to Rs1 126bn.

The minister announced a slew of initiatives to boost passenger amenities, especially IT improvements including more online ticket booking and reservations. He hopes to raise funding for investment through PPPs and foreign direct investment, for which IR is seeking Cabinet approval.

With studies underway for high speed rail in corridors such as Mumbai – Ahmedabad, Gowda identified nine routes which would be upgraded to permit passenger trains to operate at 160 to 200 km/h:
  • Delhi – Agra;
  • Delhi – Chandigarh;
  • Delhi – Kanpur;
  • Nagpur – Bilaspur;
  • Mysore - Bengaluru – Chennai;
  • Mumbai – Goa;
  • Mumbai – Ahmedabad;
  • Chennai – Hyderabad;
  • Nagpur - Secunderabad

When India decided to make the gauge change from 1000mm gauge earlier, why did it not change to the standard gauge? It thought it will make sense for the world to gravitate towards the standard gauge whenever they want to make gauge changes. It will also be cheaper to construct than the wider gauge that India is adopting now.

Any insights?

Thanks.

It only makes sense when introducing a new rail gauge anyway, to choose a gauge for which abundant equipment is available.

But the problem for India with 1000 mm gauge is that it receives inferior service compared to 1676 mm network, because it is smaller network.

Thus introducing a completely new gauge to India would make service on the existing 1000 mm railways even worse.

Which is why India should stick to broad gauge.

In south Asia due to its huge population Broad gauge was introduced by the British along with meter gauge and narrow gauge. Unification of guages was introduced later to make the network in just one gauge. In south Asia Both Pakistan and Banglades runs train Broad gauge along with meter gauge. As Bharatbarsh from primitive civilized era has a natural mountain border from rest of the world, So there is no problem to connect them by rail
In INDIA 91% of track length and 86% of route length is broad gauge(1676 mm) and after 3-4 years more than 96% track Km will be Broad gauge. The remaining left routes will either in the hilly region or not physical to convert.

Changing to standard gauge for the meter gauge would only make sense if the rest of the network would be changed to standard gauge as well. Which it won't.
While I do like that parts of Africa are switching over to standard gauge, it is only a viable option since the systems are relatively tiny, most lines there need replacing anyway and there is often gauge differences across borders. India on the other hand has a large, heavily used system using track and loading gauges that mean good things for capacity and speeds (broader rail gauge leading to inherently more stability at high speeds than narrow ones).

How far into the neighboring countries does the Indian gauge stretch?

In Argentina and Chile the majority of tracks is in broad or indian gauge 1676 mm

Does broad gauge really mean larger capacity? What's the real advantage of a broad gauge system?

It's very stable, that's why those services can hit 140km/h plus on tracks with really quite poor condition.

Pakistan: 1676 and 1000 mm networks.
Iran: 1676 mm railway from Quetta over border to Zahedan, which is break of gauge to 1435 mm
Sri Lanka: 1676 mm railway (narrow gauge is 750 mm). A ferry connects railheads, but apparently does not carry trains, nor does a bridge cross all over Adam´s Bridge.
Bangladesh: 1676 and 1000 mm networks
Burma: 1000 mm network but no overland rail to India or Bangladesh
Nepal: 1 railway Raxaul-Sirsiya (6 km), converted recently from 1000 to 1676 mm.

I think that there are currently no rail connections over the borders India-China, India-Bhutan, Nepal-China, Pakistan-China or Pakistan-Afghanistan.

Sopomon is right and I'd like to add that India not only has a broad rail gauge but also a wide and tall loading gauge. I.e. the train cars can be wider and taller without hitting station platforms or overhead bridges.
wiki link

EDIT: if e.g. the UK had the same loading gauge as India it would mean they could run trains with one more seat per row and double decker trains. These days it would be needed on several lines. But since the UK has among the most restrictive loading gauges since some lines are ooold they can't fit such cars on their network.

It is not UK that has a loading gauge. It is GB. Ireland, incl. North Ireland, has a broader gauge - 1600 mm.

Back in 1846, UK had to decide on gauge unification. Since they already had so much 1435 mm tracks in Great Britain, they decided on 1435 mm for Great Britain. But there was not much 1435 mm in Ireland yet - and UK recognized 1435 mm was a mistake, and too narrow. They were not going to build railway between Great Britain and Ireland anyway, so they standardized Ireland on 1600 mm, and regauged the short 1435 mm railway that had already been built in Ireland. And when they built brand new systems that could not run through to Great Britain anyway, they chose 1676 mm both in Canada and in India.

Great Britain is also stuck with a very narrow loading gauge. Actually much of the narrow track gauge network of the world has a wider loading gauge than Great Britain - South Africa, Australia and Japan all have narrow gauge networks on wider loading gauge.

Pakistan-Afghanistan : you have the Khyber Pass railway, but not sure it is
still active...

Afghanistan is going to become a strange beast, as it will soon have railways
with 3 different gauges :
- russian gauge from Turkmenistan (Towraghondi, and a second one in construction)
- russian gauge from Uzbekistan (Termez)
- standard gauge from Iran under construction
- indian broad gauge from Pakistan

Afganistan decided to construct its rail line with standard guage. So they can use Iran ports for their export. note that they donot have mountain in the broder of Iran which they have with pakistan

Out of order since 2006. But the terminal station Landi Khana is on Pakistan side, so no railway on Afghan side.

There are no inter-country railway lines in South Asia because of security reasons.

The line from Hairatan to Mazar-i-Sharif is russian gauge, 75 km long, and
opened since 2012. The line from Khaf to Herat, standard gauge, is 77 km
long, and supposedly "under contsruction" since almost a decade. So for the
time being, there doesn't seem to be a very apparent domination of the
standard gauge around there...
