Railways to electrify its entire broad gauge network in 2 years: Government – PTI

NEW DELHI: The Railways has set a target of 2021-2022 to electrify its entire broad gauge network, railway minister Piyush Goyal told Parliament on Wednesday.

Replying to a question in the Lok Sabha, Goyal said the national transporter has 28,810 route kilometers left fore electrification.

"The Ministry of Railways has planned to electrify balance broad gauge routes of the Indian Railways by 2021-22, " he said. Railway minister Piyush Goyal. (PTI)

Among those which will be electrified during this period are the Northeast Frontier Railways' 2,779 RKM, South Western Railways' 2,702 RKM and the Western Railways' 2,633 RKM.

"No new infrastructure for production of diesel locomotives has been proposed by Railways after the decision of 100 per cent electrification in September, 2018. Diesel locomotives that will be manufactured at Diesel Locomotive Factory Marhowra shall be required by Indian Railways for strategic, emergency and certain operational reasons, " Goyal said.

Indian Railways tracks by SAIL not fit for 160 kmph passengers trains operations: US university study

By: Saurabh Kumar | Published: June 28, 2019 12:55:02 PM

Even as the ministries of railways and steel are at loggerheads over the volume and quality of rails being supplied by SAIL — the issue is now before the Cabinet secretary — a study by a technical institute at the University of Illinois has showed that the current tracks manufactured by the PSU are not suitable for the 25-tonne axle load freight operations the transporter wishes to upgrade to beyond 50 kmph.

Also, these rails are not suitable for high-speed (160 kmph) passengers operations.

In fact, the study also shows that the current tracks are not suitable to run freight trains of lower 22.9 tonne axle load, which are currently used by the railways beyond 60 kmph.

SAIL has an exclusive contract to supply rails to the transporter.

The Cabinet secretary, as directed by the Prime Minister’s Office, will be soon holding a meeting of the parties involved to sort the issue. The railways in its 100-day agenda has decided to move to high-speed in at least the Delhi-Mumbai and Delhi-Kolkata routes.

The report has observed, “As a point of comparison, the IR’s 880 Mpa rail is of lower strength than even the standard grade used in the US. As such, given the importance of rail as an asset from both the safety and reliability point of view of IR’s operation of both passenger and freight trains on the same infrastructure (rails), TTT recommends the use of higher strength rails.”

The study was commissioned by the railways (IR) to check the findings of the Research Designs & Standards Organisation, a part of the railways, which has recommended use of 1,080 Mpa rails.

The findings of the Transportation Technology Transfer Technical Report have already been presented to steel ministry officials.

Emails sent to SAIL and the ministries of railways and steel remained unanswered.

A source, requesting not to be named, clarified the plants of SAIL in Bhilai were built to service the railways only and they produce 880 Mpa rails as that is the requirement given by IR. “SAIL has research and development teams which develop new grades. If IR sends a request for higher grade, the firm will be able to upgrade, but that cannot happen overnight,” said the source.

The technical report, however, has recommended to “consider use of 1,080 Mpa rail. The existing IR track structure having a rail section, of 60 kg/m and 880 Mpa tensile strength, is not adequate for 25 tonne axle load operations. Given the current estimates of rail stresses, the use of 1,080 Mpa rail with a minimum rail strength in the range of 880 Mpa provides better coverage against a combination of rail stresses and the potential for rail failures compared with 880 Mpa rail.

“Additionally, the incremental strength increase from 880 Mpa will have disproportionately positive impact on 1,080 Mpa rail’s service life. This specification and procurement decision should be considered in terms of the life cycle cost, but the benefits are likely to justify its worth”.

The tracks used now by IR are not unsafe for both passenger and freight movement albeit at low speeds. However, this dampens the ambition of reducing travel time on the network.

The railways has a meagre 35% share of the freight traffic due to abysmally low speeds of trains moving at an average of 25 kmph. “This leads to inordinate delays. In fact, there is a demand to run freight trains of 22.9 axle load at 75 kmph, but railways cannot allow it,” said a government source.

The other tussle that SAIL and IR are engaged in is adequate supply of rails. Despite the railways requiring 14-17 lakh tonne every year to upgrade its existing tracks and build new ones, supply from SAIL has fallen short. In the last financial year, SAIL supplied 9.85 lakh tonne.

The transporter has floated global tenders twice to procure rails from abroad, but both the attempts failed as the specifications required by the railways were not available, in the process slowing down the process of track renewals — putting in question the passenger safety.


vsunder saar can probably answer this...it seems like the Steel mechanical properties required by IR is not available in global market? But the article & SAIL's version seem confusing. If IR has floated global tenders twice, was SAIL excluded from taking part in the tenders? If not, what has prevented SAIL even responded to the tender? In the article, SAIL has said that it has capability to develop the newer steels but is waiting for official (?) request from IR. Doesn't the global tender constitute as an official request?

^ Sir dont forget LCA was also not flight worthy and letters were sent to GoI on urgent basis. We have to validation the tracks on a small scale first and decide accordingly then depending upon external studies - of course no wants to lose their business. So all is well!!

Delhi Bhopal Shatabdi runs at 150kmph + may have even touched 160kmph during its runs. Tons of videos online on this.

Vande Bharat express was tested up to 180+kmph across different stretches including Delhi Kota with full complement of equipment, people.

Talgo trains were tested at 180+kmph across stretches.

IR Research organization has already recommended higher quality steel.

This study looks like nothing but an attempt to spend some money to get some stale opinion. Why would you ask a US university to conduct this study? Why not the Japanese? The French? The Germans? Of all the developed countries US perhaps has the least developed train network.

unless we have ultrasonic track testing machines frequently checking all high speed tracks, I think its time for the much delayed move to heavier longer rails for all of IR and make the necessary arrangements for our steel plants to supply. surely tata-corus will also have this tech.

Chetak if you make a road trip on west coast, drive from honnavar on KA coast via jog falls & sagar to sivamoga. very scenic route. visit the bhadra wildlife park. north of honavar is karwar and south is the beautiful giant shiva temple of murudeshwara and the sea+river drive of maravanthe.



IR wants to electrify all tracks in next 2 years - which means drumroll all BG tracks in NE.

Indian Railways to offer additional 4 lakh seats per day, thanks to new technology

More than four lakh additional berths will be available to passengers everyday from October when the railways will move to a technology which will help it generate power from engines, rather than power cars, for lighting and air-conditioning, senior officials said today. Currently, there are one or two power cars at the end of every train in every LHB rake where the electricity to be supplied to coaches is produced in a diesel generator, known as End on Generation (EOG), officials say.

The new technology, "Head on Generation" (HOG), is used worldwide, by which power supply is tapped from overhead power lines and distributed to train coaches. Officials say by October 2019, over 5,000 coaches of the Indian Railways will operate on the new technology. It will not only enable trains to shed their power cars and make way for more coaches but also save the national transporter more ₹6,000 crore in fuel bills annually, they say.

A power car needs 40 litres of diesel per hour per non-AC coach while an AC coach needs 65-70 litres of diesel per hour. Around three units of electricity is provided by one litre of diesel, so a non-AC coach uses around 120 units of electricity per hour.

The new system, which is eco-friendly, with no air or noise pollution will reduce carbon emissions by 700 MT per year per train, officials said.

"In regular practice, two power cars equipped with Diesel Alternator sets are placed at either ends of the rake run in for example every Shatabdi Express. After we move to the HOG system, there is need of only one power car for standby purpose only.

"Another power car can be removed and replaced with an extra passenger coach without increasing the train length. Once all LHB coaches are on this system, we have calculated an increase of more than four lakh berths everyday through this and thus additional revenue as well," said an official.

https://www.livemint.com/news/india/sec ... 21184.html

New Delhi: The much-awaited second Vande Bharat Express will be run on the high traffic Delhi-Katra route three days a week, likely from next month, sources said Monday.

The Delhi-Katra route was chosen by the Railway Board in a bid to capitalise on the high traffic volume owing to the Vaishno Devi temple pilgrimage, they said.

The high-speed train will bring down the travel time between Delhi and Katra, the last station on the way to Vaishno Devi temple, to eight hours from 12 hours it takes currently.

The first Vande Bharat Express or Train 18 was launched on the Delhi-Varanasi route.

The second Vande Bharat Express is proposed to be run three days a week, which could be extended up to five, they said.

"The train will run every Monday, Thursday and Saturday for now. However, depending on the demand, we might extend it by two more days," said the source.

The train will leave from Delhi at 06:00 hours and reach Katra at 14:00 hours. On its return journey, it will leave Katra the same day at 15:00 hours and reach Delhi at 23:00 hours.

Running at a maximum speed of 130 kmph, the train will have around two-minute halts each at Ambala, Ludhiana, and Jammu Tawi, before Katra.

The train has undergone trials on the Delhi-Katra route, which was chosen among others such as Delhi-Amritsar and Delhi-Chandigarh that were also in the contention for the premium service.

Unlike its earlier version, which was criticised for lack of adequate space for pantry, the upgraded train has more space to store meals for passengers.

It has adjustable seats and improved washbasins, a sturdy aluminium-clad nose cover to avoid damage due to cattle run-over and special anti-spall film on windows to guard against stone pelting.

The first Train 18 was launched on February 15 on the Delhi-Varanasi route. It runs five days a week.

Currently, the second train is undergoing additional trials.

Vande Bharat being run on Delhi - Katra route besides tugging at emotional strings also means real convenience.

A typical trip to Vaishno Devi would be like this - you board Pooja Express around 11 pm from Old Delhi Railway Station. Reach Jammu Tawi around 11-12 am next day morning. Take bus from Jammu Tawi station to Katra that in all probability would spend some time at Jammu Bus stand too. By the time you are deposited at Katra bus stand, it shall be 2 pm in the afternoon. All in all 15 hours - which shall be reduced to 8 hours. This is truly amazing.

I last had darshan of Maa Vaishno Devi in 2009. So things may have changed but not too much from above.

Can't wait for Vande Bharat Express for Katra to start.

We need a Vande Bharat between Bangalore and Chennai, between Mumbai and Pune and between Bangalore and Secunderabad. The last one may be difficult because of the single unelectrified track.

Pooja Express drops you at JAT around 8:30am.

Vande Bharat timings are great. You can do the complete visit in flat 2 days.
Board at 6:00am, be at Katra at 2:00pm, check in to hotel at 2:30pm
Start climb at 5:30pm
Back in Hotel at 4:00am
Rest and take the train back at 3:00pm to arrive in Delhi at 11:00pm.

Railways Introduces New Tender System For ‘Train 18’, 40 Vande Bharat Train Sets To Be Produced Over Next 3 Years

In a bid to introduce a new system that provides all bidders a level playing field and ensuring transparency, the Indian Railways has introduced new tender system for the production of third rake of Train 18 (also called the Vande Bharat Express), The Financial Express reported.


Its on again... :lol:

While Train 18’s first rake was manufactured in a record time of just 18 months at an estimated cost of around Rs 97 crore, the Railway Ministry received nearly 25 complaints from multinational companies and vendors that a domestic private company was allegedly favoured in the procurement process for the train set’s electrical equipment.

Immediately there was a problem :lol:
