background
Background
  • Indian Railways :
    • Fourth Largest Rail Network in the World
    • Largest Network on basis of No. of Passengers carried per Km.
    • Route Length – 63000 Kms.
    • Track Length - Over 100,000 Kms
    • Almost 15,900 Girder Bridges using over 900,000 Wooden Sleepers
background4
Background

Need for a New Material was felt because :-

  • Though Wooden Sleepers had performed well all these years, but there is a shortage of wood due to ban on felling of trees in India for Environmental Conservation
  • Steel Channel (Metal) Sleepers were developed but had following disadvantages :-
    • Poor performance in Highly Vibrating Environment of Rail-Wheel Interaction
    • Poor performance and Need for additional insulation in Track-circuited Areas
organisations involved
Organisations Involved
  • R&D Establishment (Engineers), - R&DE
    • A laboratory under the Defence Research & Development Organisation (DRDO), Ministry of Defence involved in Structural Engineering and its scope of work includes developing new designs, materials etc for Bridges.

The Research, Design & Standards Organisation (RDSO)

    • An autonomous body under the Ministry of Railways, Govt. of India
    • A single body responsible for maintaining and drafting standards for all the materials being used by Indian Railways.
    • Also involved in Research & Design for new materials, designs etc for the Railways. It has various directorate, each of which individually handles functions.
    • The Bridge & Structure Directorate of the RDSO was involved during the Project.
organisations involved6
Organisations Involved
  • The Advanced Composite Mission, TIFAC (ACM)
    • An autonomous organisation under the Dept. of Science & Technology, Government of India. The ACM under the aegis of TIFAC is working on developing marketable and sustainable new products.
    • The project was presented to ACM by R&DE and was approved
    • Financial Assistance in the form of a soft loan was provided for the project and an Advisory & Monitoring Committee (AMC) was formed.

advisory monitoring committee
Advisory & Monitoring Committee
  • The Project was presented to the ACM of TIFAC and was approved and then promoted by the ACM to the Railway.
  • Financial Assistance in the form of a soft loan was provided for the project
  • An Advisory & Monitoring Committee (AMC) was formed.
  • This powerful AMC comprised of
    • A Member of Railway Board
    • Senior officials from Bridge & Structures Directorate of RDSO, Indian Railways
    • Other senior officials nominated by Indian Railways
    • Senior Officials from R&DE
    • Officers from TIFAC
    • Personnel from PWL.
  • The responsibility of the AMC was to monitor the progress of the project and regular meetings were held to expedite the project.
the project timeline
The Project Timeline
  • 1997 : Project undertaken by RDSO and R&D Engineers, Pune with assistance from Advanced Composite Mission, TIFAC (Dept. of Science & Technology) to develop an alternative to Wood & Steel Sleepers
  • 1997 : Enquiry received by Permali Wallace Ltd. From R&D Engineers. After a series of Techno-commercial discussions, PWL was then chosen as the Industry Partner. The design was finalized after series of sessions by all the above.
  • May, 1998 : Formal PO for manufacturing 12 Sleepers received.
  • Aug.,1998 : 1st Prototype of the sleeper submitted to R&D Engineers . After initial inspection remaining 11 were produced and submitted
the project
The Project
  • 1998-99 : These sleepers were given to RDSO for Extensive Static & Dynamic Testing by R&D Engg.. These sleepers withstood testing upto 2 million cycles and were then withdrawn. They were found to be in perfect state.
  • 2000 : RDSO placed an order for 44 nos. sleepers vide their order no. SP3/0062/B&S/0048
  • 2001 : These were supplied to RDSO for extensive field trial between Feb. & May, 2001
    • First 22 fitted by Northern Railway at Najimabad on 15/04/01
    • Next 22 fitted by South Eastern Railway at Chengail on 8/6/01
  • 2002 : The sleepers have given excellent performance to date – acknowledged by RDSO vide their letter to us and also recommended the product for approval vide their letter no. CBS/DSD dt. 31/5/02
advantages of frp sleepers
Advantages of FRP Sleepers
  • Light Weight
    • Only 54 Kgs. + fittings (Net wt = 66 Kgs.)
    • Easy to Handle, Replace, Fit
  • Life of min. 40 to 50 years
  • Low Maintenance
    • Corrosion free
    • Unaffected by adverse environmental conditions & UV Rays
  • Insulating Material – extremely suitable for track circuited areas
  • Lowest Cost – on basis of Life Cycle Cost
conclusions
Conclusions
  • Lowest life cycle cost as compared to other sleepers
  • Number of other inherent advantages as discussed
  • Full scale commercial use by Indian Railways is on the anvil
  • Permali Wallace Pvt. Ltd. Is fully equipped to meet the Global requirement with necessary infrastructure for mass production in its place
  • The product was nominated in the Mass Transit Category during the JEC 2004 Awards
  • FRP Sleeper : A Solution for future
our other products for tracks
Our Other Products for Tracks
  • Permaglass Fishplates

These electrically insulating Fish Plates are used in the marshalling yards of Railways where automatic track signaling is in use. The Fish Plates are mechanically strong and join the two rails and simultaneously insulate them electrically

third rail current collector beam
Third Rail Current Collector Beam
  • An undercarriage Fitment, when assembled with other components is used on Metro rail. The assembly collects current, from the third rail laid next to the main rails, to be transmitted to the traction motors. This is a critical component since human safety is involved in the application.
