Talgo Train And Metrino Pod :-The Rail and Road in 21st century India:-
One of the major focus areas of the railway minister so far has been to reduce travel time by increasing the speed of the trains. The bullet train is a long term project. In the short term, he is focusing on how speeds can be increased without having to spend a bomb on revamping current infrastructure.
Towards that objective Indian Railways conducted the first trial run of Spanish Talgo train on the Bareilly-Moradabad rail route. Though it is capable of hitting a maximum speed of 200 Km/hour, the oscillation test was conducted at 115 Km/hr. The next trial will take place on the Mathura-Palwal route at a maximum speed of 180 Km/hr. This will be followed by the time validation trial on Delhi-Mumbai corridor. It is expected that the travel time will come down by at least five hours for this route when Talgo coaches are used.
Talgo Train :-
The concept
If one notes a racing track, the curves are ‘banked’, i.e. the curves are raised on the outer side, which makes the vehicle run inclined on them. If one doesn’t raise the outer side, a fast moving vehicle might fly off outside. This banking is done for a certain speed, if you bank too high and drive slow on it-one might just topple inside (think of a velodrome-can a cyclist drive slow on the curve?). Trains being big vehicles, would not easily fly off or topple easily.
The IR network is shared between slow moving freight and faster passenger trains. This created problems for engineers as they have to cater not only to the fast moving rajdhani/ shatabdi type trains but also to the slow moving goods trains.
When the train travels at faster speeds on curves not banked for that speed, the passengers in the train are discomforted, which limits the maximum speed potential of each curve. Trying to run faster trains on existing tracks is thus not easy. For high speeds, say 250 or 300 kmph, new tracks with flatter curves are generally laid.
For higher speeds, this discomfort can be overcome without modifying the tracks, if the vehicle is also tilted by right amount when the curve is negotiated. This tilting can be done by using actuators which tilt the vehicle body when a curve is sensed. Talgo comes with a natural tilting technology, a clever concept, where the superstructure of the coach tilts while negotiating a curve without powered actuators.
Talgo hopes to use tilting trains to negotiate curves at higher speed and achieve better run times.
Talgo makes coaches with patented design of wheel assemblies. Unlike, conventional rolling stock, the two wheels are not mounted on a fixed axle. Thus, the two wheels can rotate independently of each other, which reduces lateral forces (forces which sway the vehicle perpendicular to the direction of motion).
The energy saving of 30% as talked in several press releases is a bit overplayed and needs to be taken in with due caution. Another key aspect is the light weight of the coach due to use of aluminium and its alloys. This reduces the deadweight of the coach and makes it more energy efficient. This aspect of coach weight reduction can be implemented on all types of stock even without Talgo’s patented wheel arrangement.
Energy saving from a passive rolling stock occurs essentially on account of its lower mass (less weight to be accelerated and braked-more pronounced if sections are undulating or graded). Another energy saving component is the reduced number of wheels. Reduction of wheels happen by making two coaches share a pair of wheel under the vestibule.
#1 Physics mandate that the curves on road/tracks be banked (for certain speeds), otherwise a fast moving vehicle may fly outside (or topple inside if too slow). But trains are big and heavy and won’t topple easily but can cause discomfort to passengers. So running faster trains on Indian tracks can be risky. However, Talgo comes with natural tilting technology which tilts it by the right amount when it senses a curve. So, travel time can be cut drastically with minimum investment.
#2 The coaches are energy efficient due to two reasons. First, because of the light weight thanks to the use of aluminium and its alloys in its manufacturing. Second, because of the reduction in number of wheels as two coaches share a pair of wheel under the vestibule.
Another advantage is that due to its low weight, the train will accelerate more with less power requirement.
#3 A typical-20 coach Rajdhani has 80 axles, whereas a 37 Talgo coach train of similar length would have about 37-40 axles. So, Talgo saves on number of axles per train.
There are some concerns too.
#1 The Talgo coaches are shorter, about 13m as against LHB (Current Indian Railway stock) of 22 m. So, a 37-coach Talgo train is considered equivalent to a 20-coach Rajdhani.
#2 Talgo is a bogie-less design. It has been around for a long time but no major operators and manufacturers have employed it.
#3 Currently, a defective coach can be detached and a new one attached enroute. But in Talgo trains, this is not a possibility as two coaches share a pair of wheel.
However, the prospective benefits currently outweigh the concerns. Suresh Prabhu is targeting an investment not easy to come by. The biggest benefit of Talgo is that it obviates the need to lay new of Rs 8 lakh crore over the next five years to completely transform the railways but this is tracks and drastically reduces the travel time.
If the tests are successful, it will usher in new era for the Indian railways and train passengers.

Metrino Pod taxis
Transport minister is experimenting with interesting ideas too. One such idea is introducing Metrino pods on the Delhi-Gurgaon corridor. Last month, the Union Government gave its nod to the National Highway Authority Of India (NHAI) to go ahead with the project.
The pod taxi service is cost-effective, takes a lot less time to build compared to metro and monorail and doesn’t need any significant infrastructure investment.
Necessity is the mother of invention, they say. Crunch of funds has forced both Prabhu and Gadkari to go for these cost-efficient options.
It’s a long way to go before we can pass judgments on the successes or failures of these experiments. For instance, the jury is still out on Metro even after its debut 15 years ago.
But one thing is sure. Both the ministers are trying their best to drag the Indian transportation to the 21st century.
Rare seabird flies into camera view
The earliest record of the bird is from the Andaman Islands dating back to 1870s at Ross Islands.White-tailed tropicbird (Phaethon lepturus), rare in India.
A paper on Indian Rarities 1 (in the journal Indian Birds: Journal of South Asian Ornithology) that said the bird, a pelagic, has been recorded eight times in the past 150 years in the Indian sub-continent. Pelagic birds frequent a zone of the sea or lake that is neither close to the bottom nor near the shore.
Phaethon lepturus is the smallest of the three tropicbirds recorded in Indian subcontinental waters. The species is a known resident on the Maldives archipelago and has been recorded as a vagrant visitor to the coasts of India and Sri Lanka in the past.
North Eastern Council likely to be upgraded as resource centre
- Prime Minister Narendra Modi, during the recently held the North Eastern Council Plenary meeting, hinted at the possibility of upgrading the North Eastern Council (NEC) as a state-of-the-art resource centre capable of meeting the aspirations of the people.
- He also dedicated to the nation the Doppler Weather Radar at Cherrapunji.
- The North Eastern Council is the nodal agency for the economic and social development of the North Eastern Region which consists of the eight States of Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura. The chief ministers and governors represent them.
- The headquarters of the council is situated in Shillong, and it functions under Ministry of Development of North Eastern Region(DONER)
- The North Eastern Council is a statutory body.

- The world lost more than 10 million hectares of primary tropical forest cover last year, an area roughly the size of Switzerland.
- Ending tropical and subtropical forest loss by 2030 is a crucial part of meeting global climate, biodiversity and sustainable development goals. Protecting tropical forests offers one of the biggest opportunities for climate action in the coming decade.
- Tropical forests are massive carbon sinks and by investing in their protection, public and private players are likely to stock up on their carbon credits.
- The LEAF coalition initiative is a step towards concretising the aims and objectives of the Reducing Emissions from Deforestation and Forest Degradation (REDD+) mechanism.
- REDD+ was created by the United Nations Framework Convention on Climate Change (UNFCCC). It monetised the value of carbon locked up in the tropical forests of most developing countries, thereby propelling these countries to help mitigate climate change.
- It is a unique initiative as it seeks to help developing countries in battling the double-edged sword of development versus ecological commitment.
- The initiative comes at a crucial time. The tropics have lost close to 12.2 million hectares (mha) of tree cover last year according to global estimates released by Global Forest Watch.
- Of this, a loss of 4.2 mha occurred within humid tropical primary forests alone. It should come as no surprise that most of these lost forests were located in the developing countries of Latin America, Africa and South Asia.
- Brazil has fared dismally on the parameter of ‘annual primary forest loss’ among all countries. It has lost 1.7 mha of primary forests that are rich storehouse of carbon. India’s estimated loss in 2020 stands at 20.8 kilo hectares.
- Between 2002-2020, Brazil’s total area of humid primary forest reduced by 7.7 per cent while India’s reduced by 3.4 per cent.
- Although the loss in India is not as drastic as in Brazil, its position is nevertheless precarious. For India, this loss is equivalent to 951 metric tonnes worth carbon dioxide emissions released in the atmosphere.
- It is important to draw comparisons between Brazil and India as both countries have adopted a rather lackadaisical attitude towards deforestation-induced climate change. The Brazilian government hardly did anything to control the massive fires that gutted the Amazon rainforest in 2019.
- It is mostly around May that forest fires peak in India. However, this year India, witnessed massive forest fires in early March in states like Odisha, Uttarakhand, Madhya Pradesh and Mizoram among others.
- The European Union’s Copernicus Atmospheric Monitoring Service claimed that 0.2 metric tonnes of carbon was emitted in the Uttarakhand forest fires.
- Implementation of the LEAF Coalition plan will help pump in fresh rigour among developing countries like India, that are reluctant to recognise the contributions of their forest dwelling populations in mitigating climate change.
- With the deadline for proposal submission fast approaching, India needs to act swiftly on a revised strategy.
- Although India has pledged to carry out its REDD+ commitments, it is impossible to do so without seeking knowledge from its forest dwelling population.

According to the UN-REDD programme, after the energy sector, deforestation accounts for massive carbon emissions — close to 11 per cent — in the atmosphere. Rapid urbanisation and commercialisation of forest produce are the main causes behind rampant deforestation across tropical forests.
Tribes, Forests and Government
Disregarding climate change as a valid excuse for the fires, Indian government officials were quick to lay the blame for deforestation on activities of forest dwellers and even labelled them “mischievous elements” and “unwanted elements”.
Policy makers around the world have emphasised the role of indigenous tribes and local communities in checking deforestation. These communities depend on forests for their survival as well as livelihood. Hence, they understand the need to protect forests. However, by posing legitimate environmental concerns as obstacles to real development, governments of developing countries swiftly avoid protection of forests and rights of forest dwellers.
For instance, the Government of India has not been forthcoming in recognising the socio-economic, civil, political or even cultural rights of forest dwellers. According to data from the Union Ministry of Tribal Affairs in December, 2020 over 55 per cent of this population has still not been granted either individual or community ownership of their lands.
To make matters worse, the government has undertaken systematic and sustained measures to render the landmark Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006 ineffective in its implementation. The Act had sought to legitimise claims of forest dwellers on occupied forest land.
Various government decisions have seriously undermined the position of indigenous people within India. These include proposing amendments to the obsolete Indian Forest Act, 1927 that give forest officials the power to take away forest dwellers’ rights and to even use firearms with impunity.
There is also the Supreme Court’s order of February, 2019 directing state governments to evict illegal encroachers of forest land or millions of forest dwellers inhabiting forests since generations as a measure to conserve wildlife. Finally, there is the lack of data on novel coronavirus disease (COVID-19) deaths among the forest dwelling population;
Tardy administration, insufficient supervision, apathetic attitude and a lack of political intent defeat the cause of forest dwelling populations in India, thereby directly affecting efforts at arresting deforestation.
Way Forward
Tuntiak Katan, a global indigenous leader from Ecuador and general coordinator of the Global Alliance of Territorial Communities, aptly indicated the next steps at the Climate Summit:
“The first step is recognition of land rights. The second step is the recognition of the contributions of local communities and indigenous communities, meaning the contributions of indigenous peoples.We also need recognition of traditional knowledge practices in order to fight climate change”
Perhaps India can begin by taking the first step.
