India Builds World’s First-Ever Electrified Rail Tunnel Capable Of Running Double Stack Container Trains

In a remarkable development, India has completed the building of world's first-ever electrified rail tunnel which is capable of running double-stack container trains through its passage, reports Times of India.

Located on the Rewari-Dadri section of the under-construction Western Dedicated Freight Corridor (WDFC), the one kilometre-long tunnel located in the Aravali rocky mountains in Sohna has been built in a short span of lesser than a year despite the disruption caused by COVID-19 pandemic.

Once operations begin, double-stack container freight trains with as much as 25-tonne axle load will be seen zooming through the tunnel at speeds of 100 kilometres per hour (kmph). The tunnel connects Mewat and Gurugram in Haryana, negotiating a steep gradient.

From the geological perspective, the tunnel has been deemed as safe and stable as it has been caved through 250 to 500 million-years-old proterozoic rocks which are known to have high bearing capacities.

The WDFC and the Eastern DFC are the two mammoth projects which are being pursued by the Indian Railways in a bid to transform the freight transportation in the nation. Railways aim to operationalise both the DFCs by the end of 2021.

Probably the story behind DRDO mine layer we see now

The bine burier is a drdo development and a recent product at that .

This one most probably , this was fitted behind ( towed behind ) a vehicle as mentioned in the article.

HAd a few doubts.

Wont this mean that mines are in an almost staright line? Easier to find a pattern once you discover a few

Despite the covering mechanism to again throw soil over laid mines, the freshly dug soil will be distinctly seen (unless in desert)

The first two consecutive test-firings in lofted top-attack mode of the definitive version of the third-generation HELINA anti-armour guided-missile on July 15 and 16 at the DRDO’s ITR at Balasore has finally kicked off the process of integrating the missile with the ‘Dhruvastra’ weapons-control systems on-board the Rudra WSI (Dhruva Mk.4) helicopter-gunships (78 for the Indian Army Aviation Corps or AAC, distributed among 7 Squadrons, and 16 for the Indian Air Force or IAF) and Light Combat Helicopter or LCH (97 for the AAC and 65 for the IAF).

The 7km-range HELINA’s developmental effort began back in 2012 after it was discovered that the 4km-range NAG anti-armour guided-missile will not be suitable (from a flight-safety standpoint) in a helicopter-launched configuration. In the initial round of test-firings in late 2016 and mid-2017, the HELINA’s imaging infra-red (IIR) seeker, which was derived from that of the NAG failed to acquire and engage ground-based moving and stationary targets beyond a range of 5km.
This led to the IIR seeker’s sensitivity being subjected to further improvements aimed at achieving mission effectiveness out to the specified range of 7km during both daytime and at night.

A series of user-assisted firing trials lasting eight months will kick off by the year’s end for validating the HELINA/Dhruvastra combination’s performance during both winter-time and summer-time over different kinds of terrain and at different operating altitudes. Following this, by late 2021 the Rudras and LCHs will start receiving the series-production HELINA/Dhruvastra combinations.

t may be recalled that the first Rudra prototype made its maiden flight in August 2007. After a series of flight and weapons trials lasting almost six years, the 5.5-tonne Rudra achieved Initial Operational Clearance (IOC) in February 2013. The first two Rudras were officially handed over to the AAC during the Aero India 2013 expo at Yelahanka, Bengaluru. Since then, it has taken almost another eight years for the Rudra to emerge as a fully weaponised helicopter-gunship for delivering immediate air-support to the Indian Army.
**************
It is also expected that the IA, which has to date ordered 443 Bharat Dynamics Ltd-built third-generation NAGs along with 13 OFB Medak-built NAMICA-2 tracked missile launchers, will decide against ordering additional NAGs and will instead opt for the longer-range HELINA for its follow-on NAMICAs.

Also under development is a DRDO-developed fire-and-forget millimetre-wave (MMW) W-band seeker for a 12km-range version of the HELINA, called SANT. However, the R & D cycle of this missile is unlikely to be completed by 2021 at the very latest.

otal orders for the HELINA for both the IA and IAF are expected to exceed 8,500 units, while for the SANT the requirement is for 4,000 units

So more than 400 Nag ATGMs have already been ordered by the Army? Thought it never went beyond DAC clearence in 2018.

Bdw only he is the first to report.............I have asked many ...but all were clue less...if namica can fire 7 km helina..then it's good..... though only baba banaras confirmed many times that ia used nag atgm

In 2018, the DAC had approved 300 Nags and 12 NAMICAs but nothing got reported after then as if it's something shameful that needs to be hidden. If the same amound of Spikes would have been ordered, the chest thumbing and celebrations would have known no limits.

Super power in importing and back bitching own products



Proponents of an indigenous defence industrial base say fast-track imports are like a foot in the door and gradually expand into larger orders, diverting limited budgetary resources. The army is close to placing a second order of 72,000 battle rifles from US arms-maker SIG Sauer, after an identical purchase last year. Indian manufacturers who have invested in developing domestic capabilities to design and develop small arms are aghast. “FTPs strike the biggest blow to Indian industry.


When the armed forces go for foreign weapons, even small arms, you are effectively telling the world that your indigenous capacity is worthless. When we try and export, the first question we are asked is ‘why isn’t your own army buying your products’,” says the CEO of a private sector firm.


The Defence Research and Development Organisation (DRDO) is worried that an order for a regiment (45 vehicles) of Russian 2SDS ‘Sprut’ light tanks for use in high-altitude terrains like Ladakh will kill its own under-the-wraps light tank project. The infantry wants more Israeli-built ‘Spike’ anti-tank guided missiles (ATGMs) even as the DRDO is readying an indigenous man portable anti-tank guided missile (MPATGM) for the army.


A bulk of the current fast-track buys are for ammunition. The shortfalls, army officials say, have been caused by the Ordnance Factory Board (OFB), whose 41 factories have failed to keep the supply lines running. The OFB is part of the defence ministry’s Department of Defence Production.


A series of Comptroller and Auditor General (CAG) reports have highlighted deficiencies in OFB-produced ammunition. A 2015 CAG report noted that 74 per cent of 170 types of ammunition failed to meet the ‘minimum acceptable risk level’ and only 10 per cent met the ‘war wastage reserve’ requirements. Another CAG audit for 2017-18 presented in Parliament in December 2019 said that the ordnance factories ‘had achieved production targets for only 49 per cent of the items’. A significant quantity of the army’s demand for principal ammunition items remained outstanding as on March 31, 2018, adversely impacting its operational preparedness, said the report. OFB exports, the report said, decreased by 39 per cent in 2017-18 over 2016-17. On May 16 this year, finance minister Nirmala Sitharaman announced that the government was corporatising the OFB to improve ‘autonomy, accountability and efficiency in ordnance supplies’. Corporatisation, though, could take several years to bear fruit. Attempts at private sector ammunition production have not taken off either, though not for want of capacity, capability or investments.

In June, the army’s Master General of Ordnance Branch inexplicably pulled the plug on a 2016 plan to procure ammunition from the private sector. A brainchild of then defence minister Manohar Parrikar, the plan had aimed to bring the private sector into what was until then a government monopoly. It studied the 2016 experience where ammunition deficiencies led to fast-track buys. The goal was not only import substitution but also to create a vast domestic ammunition manufacturing capacity that the armed forces could tap into in an emergency. Deliveries would commence from six months of signing of the contract and spread over 10 years.


Fifteen private sector firms had planned to bid for eight procurement contracts for specialised tank, anti-aircraft and infantry ammunition for the army’s vast Russian-origin arsenal of battle tanks, anti-aircraft guns, multiple grenade launchers and 155 mm artillery guns (see A Lost Opportunity). Some of the private players had even established plants and scouted for international partners, anticipating orders. Five requests for proposal (RFPs) for ammunition were withdrawn while no decision has been taken on proposals for BMCS (Bi Modular Charge System) and fuses. With the collapse of long-term capability building plans, short-term weapons acquisitions will continue to remain more attractive.

Arjun mk2 update by Trishul blog. He replied to one of the questions about it.
"Mk 2's development is now underway and the hulls and turrets of four prototypes, each made of HNS, have already been delivered to CVRDE at Avadi for electrical/mechanical accessories outfitting & systems integration. By using a Cummins 1500hp engine, the desired power-to-weight ratio of 25hp/tonne will hopefully be realised if the MBT's weight is kept limited to 61 tonnes."
