Adhesives & Sealants for Indian Railways

Indian Railways  

India’s national railway system is operated by the Ministry of Railways. It is run by the government as a public good and manages the fourth largest railway network in the world by size, with a route length of 95,981-kilometre (59,640 mi) as of March 2019.

What could be the factors that matter for the railways industry? It will be in their best interests to ensure that the trains are safe and comfortable for regular use, while also having a long lifetime. Sealants and adhesives play a lesser-known but highly significant role while manufacturing a train that meets these broad criteria. They are thus used regularly for both interior and exterior application. Sealants and adhesives are used in almost all parts of railway manufacturing. From design to production to maintenance, be it for high-speed trains to light rail transit.

Where are Adhesives & sealants used in Indian Railways

  • New Engines or Locomotives – Eg: DLW, CLW 
  • Strip Down Maintenance of Diesel Locos – Eg: DMW Patiala
  • In running maintenance of Locos- Loco Worshop – Tkd ( Tughlakabad Shed, Howrah Loco Shed, Hubli Loco shed etc.
  • Railway coach manufacturing – RCF Kathurthala, ICF Chennai, Raebarely Coach factory.  
  • Strip down maintenance of coaches- Jagidri workshop, Lucknow coach factory.
  • ‘Sick Line’ Running Maintenance of Rakes 
  • Signalling and track Maintenance.
  • station Maintenance .
  • RDSO Lucknow -approvals for any design  change or  technology change.

To hold the bodies of the trains together, very few materials work as well as sealants

Challenges for Indian Railways

Indian Railways is Nation’s largest tranporter of people and goods. It is also the largest employer. Railways is poised to grow using better technology and managment structures. So what are the chief challenges Indian Railways is working to overcome.

Safety Human lives can be compensated with anything and 8.5 billion (approx)  human lives have  been tranported in 2019. Any development, change needs to be vetted from safety officials too. 

Reduced travel time, more speed ‘ Speed is the need’ . Bullet train, Gatiman express, high speed rail tracks, fencing to ward of human and animals, 

Lighter, Stronger, Safer, faster Locomotives & coaches

Protection against Corrosion 

Track maintenance : Remote monitoring of tracks for regular maintenance and prevent sabotage 

Reduced operating cost

New track layingEspecially in the Himalayan range which includes Kashmir, Ladakh, Himachal, Uttarakhand, North East.  

Health and Hygiene 

On time running of trains, travel comfort and amenities

Dominant market share in inland freight

Because of the high vibrations, devices that harvest this energy from the railways have been pioneered.

Advantages of Adhesive & Sealants vs Conventional methods 

Being lighter in weight and offering greater adhesive strength is simply one of the advantages. We have listed some of the benefits of sealants and why they should be preferred: 

  • Strength: Sealants show a much higher adhesive strength than welded bonds or fasteners. Alongwith that being flexible and immune to hazards.
  • Application: Alternatives like welding require skilled  professionals. On the contrary, sealant or adhesive can be applied by users with basic training. It comes in bottles, cartridges, sausages, spray cans. This makes application easier. 
  • Durability: sealants and adhesives do not corrode easily under harsh climatic conditions. Thus, it makes them more suitable than other alternatives like traditional fasteners and welded bonds.
  • Eco-friendliness Sealants and adhesives of today strive to be eco-friendly. They are formulated in such a way that they contain no isocyanate, silicone, halogens or solvents.
  • Cost effective

Design • Build • Operate • Repair • Remanufacture

  • Options for new designs and innovate materials
  • New Products with upgraded Health and Safety
  • Impact and vibration resistant – the bond will endure
  • Solutions to improve durability
  • Solutions for light-weighting vehicle
  • Solutions to improve vehicle appearance
