Defence Minister Releases A Book On Historic 2800 Kms Expedition – ‘Ganga Avahan’.


  • The Defence Minister Shri Arun Jaitley released a Coffee Table Book titled ‘Ganga Avahan – The Epic Tale of a Historic Swim’, on 14th July, 2017. The ‘Ganga Avahan’ was a pioneering and historic exploratory open-water swim expedition on the Ganga River. This was the first ever human effort to swim down the entire stretch of the river and also the longest ever social campaign undertaken through an adventure sporting activity for the Swachh Bharat National Mission, Clean Ganga project and Beti Bachao Beti Padhao initiative.
  • A nine-member team of three swimmers and the rest rafters from the three Services of the Indian Armed Forces, led by acclaimed international open-water swimmer Wg Cdr Paramvir Singh was flagged-off in New Delhi by Union Minister of Urban Development, Housing and Urban Poverty Alleviation and Information & Broadcasting Shri M Venkaiah Naidu on first anniversary of Swachh Bharat, on 01 October 2015.

Key Things To Look Out For-

  • The expedition commenced on 08 October 2015, at Devprayag, where Bhagirathi and Alaknanda merge and the Ganga begins. Wg Cdr Paramvir began the expedition which continued for 43 days, through Uttarakhand, Uttar Pradesh, Bihar, Jharkhand and West Bengal and culminating on 19 November 2015 at Bakkhali Beach, Frazerganj covering a total distance of 2,800 kms. Throughout the swim, the team campaigned extensively for Swachh Bharat, Clean Ganga and Beti Bachao Beti Padhao, reaching out to the villagers, townsfolk, civic authorities and NGOs, managing to interact with tens of lakhs of people all along the route as they undertook their extraordinary and highly challenging odyssey.
  • The former Defence Minister Shri Manohar Parrikar had flagged-in the expedition on 23 October 2015. This expedition was a landmark exploration of the river as this was first time in the history of human exploration that any individual had attempted to swim down the entire stretch of the river and succeeded, making it a world record. Their other achievements included the first ever Manual Rafting of the entire river in the World and the longest ever social campaigning through an adventure activity in the World.
  • The Prime Minister Shri Narendra Modi had lauded Wg Cdr Paramvir Singh and his social outreach, during his address to the nation in ‘Mann Ki Baat’ radio broadcast.
  • The Coffee Table Book chronicles their entire extraordinary and indeed fascinating journey, detailing experiences, outreach and challenges along the vast civilizational cradle that is the Ganga. The Foreword of this epic expedition is written by the Prime Minister.
  • The function was attended by Chief of the Army Staff General Bipin Rawat, Chief of Integrated Defence Staff to the Chairman, and Chiefs of Staff Committee (CISC) Lt Gen Satish Dua besides other senior officers from the Tri- Services.

Delhi Police The First State Police To Be Equipped With ‘Super Cop Belt’.


  • National capital, New Delhi’s police will be the first state police who will get ‘super cop belt,’ a specially designed belt, widely used by Police in UK, USA, Russia and para-military forces like CRPF, CISF, NSG etc.
  • Recently, Delhi Police has flouted a tender for 10,000 belts for its officers performing ground duties.
  • This belt will help cops to keep things like Gun, Mobile Pouch, Security Batten, Wireless Set Pouch & ammunition pouch.


Key Points Of This Development-

  • Super cop belt is widely used by various police in US, UK, Russia but but Delhi police will be first state police in India to use this belt. Currently, forces like CRPF, CISF, NSG, RAF etc are using it specially while patrolling in sensitive areas. Delhi Police is trying to get 10,000 belts first then we will order further to equip all district officers.
  • Delhi Police has flouted the tender on 5th July, 2017.
  • On 6th February 2014, MHA laid down the directives regarding the super cop belt. MHA has said that these belts should have space to carry 9mm pistol and glock pistol. Delhi Police is expecting to get these belts before October this year.
  • According to the Delhi Police, currently a cop has to carry wireless set, pistol, and cartridge separately. During any protest or events which have large public gathering, these equipments become a liability.
  • In a recent case, a police constable who was posted in security unit of Delhi police, attached with a Member of Parliament lost his official pistol and 12 rounds. Later, he was arrested after an audit of weapons was done.
  • The step is seen as a major overhaul in the decaying police system of the National Capital, keeping in mind the law and order scenario of the state, which has come under criticism again and again.

Minister Of Railways Shri Suresh Prabhakar Prabhu Inducts First DEMU Train With Solar Powered Coaches Into Service Of The Nation.


  • Minister of Railways Shri Suresh Prabhakar Prabhu dedicated to the nation the first 1600 HP DEMU train with Solar Powered Coaches with a unique facility of Battery Bank on 14th July, 2017. The entire electrical need of the coaches for Lighting, Fans and Information Display System will be met from the Solar Energy produced from the solar panels fitted in the roofs of coaches. While this train has been manufactured by the Integral Coach Factory (ICF), Chennai, its Solar panels and Solar systems have been developed and fitted by Indian Railways Organisation of Alternative Fuel (IROAF) Delhi.
  • This first rake has been commissioned and based at Shakurbasti DEMU shed in Delhi of Northern Railway. Twenty-four more coaches will be fitted with this system within the next 6 months. The first rake will be put in the commercial service over the suburban railway system of Delhi division of Northern Railway


Key Points Of The Development In Railways-

  • Normally, DEMU trains provide power for its passenger comfort systems – lights and fans – from a diesel driven generator fitted on its Driving Power Car (DPC). IROAF has developed this system with a smart MPPT inverter which optimises power generation on a moving train to cater to full load even during the night. The unique feature of Battery Bank through storage battery ensures sufficient electricity when the sunlight is not available. The system helps in reducing Diesel consumption of the DPC and hence reduces carbon signature of these commuter trains by reducing CO2 generation by 9 Tonnes per coach per year.
  • A solar power DEMU train with six trailer coaches will save about 21,000 Litres of Diesel and thereby bring cost saving of Rs.12 Lac every year. Savings for a 10 coach rake with 8 trailer coaches will increase proportionately. These benefits will continue for entire 25 years life time of the rake. This will help in making DEMU commuter services better, more economical and environment friendly.
  • Solar hotel load (Lighting and Fan) system fitted on each coach is of 4.5 KWp capacity consisting of 16 Solar Panels of 300Wp each. This is adequate to power the fans and lights of the coach. The system is capable of developing up to 20 kWh per day (average) throughout the year. Surplus power generated during peak hours is stored in a 120 AH battery system. The system uses a data acquisition system and interfaces with existing hotel load power system of DEMU train. It will help in generating useful data for research for adapting the system for future rollout on all trains of IR. The system costs about Rs. 9 lakhs per coach at prototype stage.
