Chenab bridge: How project team navigated through steep slopes on horses and mules
KATRA: To realise the vision of travelling from "Kashmir to Kanyakumari" by rail, the project team behind the construction of the Chenab bridge faced several challenges. Among them was how to reach the location surrounded by the steep slopes of the Himalayas.
The team had only one option -- horses and mules.
According to Afcons Infrastructure Limited, the top infrastructure company that constructed the bridge, one of the main and earliest challenges was access to the bridge location, to transport equipment and construction materials.
"Initially, mules and horses were used by the project team to reach the location. Slowly over a period, temporary roads were created and access was made available to the site," a spokesperson from the company said.
Prime Minister Narendra Modi on Friday inaugurated the iconic Chenab Bridge, Anji Rail Bridge and Udhampur-Srinagar-Baramulla Rail Link project and flagged off Vande Bharat trains, connecting Katra to Srinagar.
The spokesperson added that eventually, on the North side of the river bank, an 11-km road was constructed and a 12-km road on the South side.
Krishnamurthy Subramanian, Executive Vice Chairman, Afcons, said the Chenab Railway Bridge is more than just a marvel of engineering. "It is a symbol of India's resolve to conquer the most formidable challenges with ingenuity and courage," he told PTI.
The company used the world's tallest crossbar cable cranes and specialised heavy machinery as tools for this ambitious project.
"The ancient and steep slopes of the Himalayas were tamed using massive consolidation grouting, making them sturdy for the colossal arch foundations," the company said, highlighting challenges it faced.
"With the foundations set, the erection of the arch from both sides was planned by the cantilever construction technique. The first big moment of triumph came on April 5, 2021, when a single majestic arch approaching steadily from both banks met at the crown," it added.
"The viaduct construction was another unique challenge. There were multiple transition areas. Keeping this in mind, the launching sequence was meticulously planned in four sections," the spokesperson said.
Giridhar Rajagopalan, Deputy Managing Director, Afcons, told PTI that for the first time in Indian Railways, incremental launching was done on a transition curve and a longitudinal gradient, both occurring at the same location, for the deck launching of the viaduct portion of the Chenab Bridge.
S Paramasivan, Managing Director, Afcons, "For Afcons, it represents our unwavering commitment to nation-building and our ability to reimagine infrastructure in the toughest terrains. This bridge will inspire generations of engineers and stands as a tribute to the power of Indian engineering and teamwork."
For the first time in the Indian Railways' history, a laboratory accredited by the National Accreditation Board for Testing and Calibration (NABL) was set up to ensure that quality was being monitored at every stage of the project.
Situated at a height of 359 metres above the river, the Chenab bridge is 35 metres higher than the iconic Eiffel Tower in Paris and the world's highest railway bridge over the Chenab river.
After inaugurating the Chenab bridge, PM Modi walked on it holding the Tricolour high. He travelled in a rail engine coach to reach the spot.

‘See huge blue ocean opportunity in India for regional jets, perfect fit between turboprops, larger planes': Raul Villaron
Hitherto a small player in India's aviation landscape, Brazilian aircraft manufacturer Embraer has its sights set on India as its next growth market—for commercial as well as defence aircraft. The company is already in the running for the Indian Air Force's (IAF) medium transport aircraft procurement project, and is also pitching its portfolio of regional commercial jets—a segment yet to take off in India—to fast-expanding Indian airlines. As part of the effort to capitalise on the opportunity, Embraer recently announced an India-focussed subsidiary. In a freewheeling interaction with Sukalp Sharma, Embraer's President and Group CEO Francisco Gomes Neto and Embraer Commercial Aviation's Head of Asia-Pacific Raul Villaron discuss the company's India ambitions and vision, including the possibility of local manufacturing. Edited excerpts: The Embraer C390 is seen as a frontrunner for the IAF's medium transport aircraft procurement project. How confident are you about winning the contract? How does the C390 stack up against competing aircraft like Lockheed Martin C130? Neto: We are convinced that the C390 is the best solution for the Indian Air Force. If you look at the last orders we got for C390—Portugal, Hungary, the Netherlands, Austria—most of them replaced the C130 with the C390 because our aircraft is more modern, faster, and carries more load. It's multi-mission by design, it is more flexible. With the C390, you can perform the same missions with less aircraft. At what stage are your conversations with the IAF and the government? When do you expect a decision? Neto: I think we're moving well. They are learning more and more about the features of our aircraft, and we believe we have a good chance, although nothing is decided…We expect a decision in a couple of years. But this is not in our hands. This is more in the hands of the Indian Air Force. If you get the IAF contract, you will be setting up an FAL (final assembly line) to build the aircraft in India. Are you also open to having an FAL here for your commercial jets as well? Neto: Everything depends on the size of the order. In the case of a C390, the expectation is to have a deal for 40 to 80 aircraft, which is a lot for that size of aircraft. If the orders (for commercial aircraft) are large enough, it would be possible for us…We are bringing a procurement team already to India because we want to explore a supply chain, even without selling many commercial jets here. We already want to find component suppliers here for aircraft to be sold in other markets. Coming to commercial aircraft, Embraer specialises in regional or small narrow-body planes. This segment did not take off in India, even as the country emerged as a massive market for larger aircraft. What is Embraer's view on the India opportunity in the segment? Villaron: We see a huge blue ocean opportunity in India, where most of the unserved markets are either too long for turboprops or too thin for (typical) narrow-bodies. We see a potential for 300 (small narrow-body) aircraft in the next 10 years, and 500 aircraft in the next 20 years in India. Historically, Indian airlines either ordered turboprops or larger narrow-bodies. We feel turboprops now have a mature network in India and there aren't many growth opportunities left. It's limiting the airlines' ability to expand regional networks because the (turboprops') range doesn't let them go beyond the short sectors. Also, with improvement in India's roads and airport infrastructure, the benefits of turboprops are eroding with time. Meanwhile, the regular narrow-bodies are upgauging (getting bigger). So, the gap between a turboprop and a typical narrow-body is widening and is becoming difficult to bridge. You want to replace a 70-seater (turboprop) due to higher demand, but a 180-seater (regular narrow-body jet like Airbus A320 and Boeing 737) has more seats (than needed). But a small narrow-body like ours—up to 146 seats—fits perfectly in that gap. Why couldn't Embraer break into India's commercial aviation market? Villaron: Embraer didn't have a strong penetration in India compared to the US, Europe, and some other markets, as our earlier E1 (series) aircraft's main value proposition was trip cost, while the seat cost was higher, which did not suit a country like India where yields are very low. But our new E2 (family of aircraft) comes with more seats, and its seat cost is very competitive—same as larger narrow-body planes—while the trip cost is still 20-25 per cent lower than theirs. Are you in active discussions with Indian airlines for your E2 aircraft? Villaron: Yes. Our main partner in India is (regional airline) Star Air (with five previous generation Embraer regional jets), and they have announced their plans to expand their fleet. So, we are talking to them to understand their needs. They took delivery of another Embraer aircraft just a month ago. The business plan and the opportunity that we see for the airline is interesting, so we are talking to them. What about major Indian airlines that are predominantly in larger narrow-body operations? Villaron: As good salespeople, we talk to everyone. We want to present these opportunities that are so clear to us. We want to make sure the airlines visualise that as well. The big ones (IndiGo, Air India, etc), I think are busy with the large aircraft orders they have placed and the expansion internationally. But they also recognise there is a need to work on the regional network. IndiGo has a turboprop fleet, which at a certain point will need to be replaced and we believe that jets are going to be the next phase of the regional network expansion in India. As for Air India, their main competitor (IndiGo) has a regional network, while they don't. So, I believe they would need to look at these opportunities. We are the leaders in the regional segment, so we are confident that we will be considered. Airbus, which has a significant presence in India, also has a small narrow-body product, A220. What is your pitch to the airlines for your E2 portfolio—E190-E2 and E195-E2—vis-à-vis the A220? Villaron: If we do a nose-to-nose aircraft comparison, the E2 is much more efficient. It's about 10 per cent cheaper to operate due to lower fuel burn. It's a much lighter aircraft, has a higher-aspect-ratio wing with better aerodynamics. It has a longer interval, so maintenance cost is lower. We use a similar engine as the A220 but because our aircraft is lighter, it stays longer on the wing…We are confident that even though our competitor is strong in India, when you compare the two aircraft, our product is better. Also, if you're looking for something that really complements the gap in India's fleet, you need to buy something from the gap, not something that's almost as big as the thing you're not looking for. The A220, with around 160 seats, is very close to a (regular) narrow-body that has 180 seats.

Rupee strengthens 11 paise to close at 85.68 against US dollar as RBI surprises with jumbo rate cut
Moreover, a surge in the domestic markets supported the rupee at lower levels with both the indices settling with gains of over 1 per cent. Forex traders said the rupee traded on a flat-to-positive note as the RBI surprised the market with a jumbo rate cut. Besides, the rate cut supported by a phased 100 basis points CRR reduction will lower the borrowing costs and boost growth. Mumbai, Jun 6 (PTI) The rupee pared initial losses and appreciated 11 paise to close at 85.68 against the US dollar on Friday, after the Reserve Bank cut repo rate by a higher-than-expected 50 basis points to prop up growth. At the interbank foreign exchange, the domestic unit witnessed heavy volatility. It opened at 85.91, registering a fall of 12 paise over its previous close. But soon pared the losses and saw an early high of 85.66 against the greenback. During Friday's trade, the rupee also saw an intra-day low of 86 and finally settled for the day at 85.68, up 11 paise over its previous close. Dilip Parmar, Senior Research Analyst, HDFC Securities, said, 'The rupee led the pack among Asian currencies, buoyed by the RBI's surprise 50 basis point rate cut. This decisive, growth-driven policy move provided a significant boost to the local currency and fuelled optimism among domestic equity investors.' However, a resurgent dollar index and weakening regional currencies could cap further gains for the rupee, he said. 'From a technical perspective, USD-INR finds support at 85.20 and faces resistance at 86.10.' On Thursday, the rupee snapped its two-day losing streak and closed 8 paise higher at 85.79 against the US dollar. The RBI slashed interest rate by 50 basis points on Friday, a third consecutive reduction, and unexpectedly reduced the cash reserve ratio (CRR) for banks to provide a major liquidity fillip to support the economy amid geopolitical and tariff headwinds. The central bank retained GDP growth projection for the current fiscal at 6.5 per cent. It also changed its monetary policy stance to 'neutral' from 'accommodative', with Malhotra saying further action will depend on incoming data. 'The RBI policy decision was pre-emptive and precise. The surprise CRR cut of 100bps despite a significantly high surplus liquidity signals a strong intent to fast-track transmission while the change in stance back to neutral reflects possible pause on future rate cuts,' Anurag Mittal, Head of Fixed Income at UTI AMC, said. Meanwhile, the dollar index, which gauges the greenback's strength against a basket of six currencies, was trading higher by 0.25 per cent at 98.98. Brent crude, the global oil benchmark, fell 0.26 per cent to USD 65.17 per barrel in futures trade. 'Any further rate cut by the RBI may also pressurise the rupee. However, a positive tone in the domestic markets may support the domestic currency at lower levels. Investors may now focus on the non-farm payrolls report from the US. USD-INR spot price is expected to trade in a range of 85.40 to 86.25,' said Anuj Choudhary – Research Analyst at Mirae Asset Sharekhan. On the domestic equity market front, the 30-share benchmark index Sensex recovered the initial lost ground and closed 746.95 points, or 0.92 per cent higher at 82,188.99, while the Nifty settled 252.15 points or 1.02 per cent up at 25,003.05. Foreign institutional investors (FIIs) purchased equities worth Rs 1,009.71 crore on a net basis on Friday, according to exchange data.
