 CORE - Committed to Mission Electrification

1. Introduction

 

 

Central Organisation for Railway Electrification (CORE) was set up in 1979 under Ministry of Railways with the prime objective of electrification of railway tracks over the Indian Railways. It was almost 40 years since its inception; the organization is marching ahead in the field of electrification by contributing 43.47% of total electrified sections of Indian Railway.

A lot of emphasis is given to Railway Electrification in recent years with a view to reduce the Nation’s dependence on imported petroleum based energy and to enhance the country’s energy security, with a vision of providing eco-friendly, faster and energy efficient mode of transportation. During the last five years, total 204 electrification projects consisting of 30964 RKM have been sanctioned by Government of India and keeping in mind the huge cost savings and considerable reduction in carbon foot print, Indian Railway has identified electrification of all BG routes as a mission area. 

Total 38,000 RKM has been identified for electrification of BG network by 2021.

 

 

 

 

 

As per study total green house gases emission from electric traction will become less than the diesel traction from 2020-21 onwards.

 

 

 

 

A blue print has been prepared by Indian Railways to electrify network with an estimated annual saving of the order of savings of Rs. 13500 crore per year past 100% electrification.  As per the analysis approximately 5.5 lakh man years will be generated during execution period of Mission Electrification. It has been established that electric trains have several advantages over diesel-powered ones.  These advantages include –

 

 

·         Reduced dependence on imported petroleum based fuels.

·         It provides energy efficient friendly mode of transports besides improving the system throughput.

·         Faster and environment friendly.

·         Reduced line hauls cost.

·         Increased sectional capacity by about 18% due to higher average speeds.

·         Reduced capital, operating and maintenance costs.

·         Offers regenerative braking resulting in saving of energy by around 20% in locomotives and around 30% in electric multiple units.

 

        EXPECTED CUMULATIVE SAVING WITH 100% ELECTRIFICATION

 

 

 

 

So far we have electrified 29288 RKMs which accounts for about 43.47% of total Route Kilometers on Indian Railways.  Presently about 54% of passenger traffic and about 65% of freight traffic is being carried on electric traction.  Status shows that the fuel expenditure for electric traction is just 36% of total fuel expenditure of Indian Railway, with electric traction accounting for Rs.9,700 crore of fuel expenditure against the total fuel expenditure of IR at Rs.26,800 crore.  This is a major indication of the economic benefits associated with electric traction.

 

CORE is also showing its commitment for mission electrification by electrifying 3155 RKM during the current year 2017-18. This is highest ever achievement in the history of this organization which is 3.14 times the electrification done in last year.

CHALLENGES AHEAD/ STRATEGY FOR ACHIEVING MISSION ELECTRIFICATION

 

The work of electrification is a specialized nature of work with limited man power and resources in the market.  The increased target of electrification requires judicious and optimal manpower and also thrust on increased productivity of existing man power.

 

The challenges for achieving ambitious milestone of mission electrification needs to be understood and CORE has devised multi facet strategies and meticulous short term and long term planning to overcome the bottlenecks.

 

 

Following multi-pronged strategies have been adopted for achieving mission electrification in a time bound manner :

 

·         The project units of CORE have been strengthened by way of enhanced delegation of power which has resulted in faster decision making and expeditious progress of electrification. 

 

The requirement for increasing pace of electrification necessitated deployment of existing man power across various projects which has paid dividends in the form of increased output from the existing man power.

 

 

·         Conventional mode of tendering has been switched over to EPC mode of contract which is by its very nature of delivery module (i.e. preparation of designs & drawings, procurement of all the materials, it’s erection and commissioning with physical and financial milestone in a agreed time frame) proves to be an ideal solution in the face of serious constraint of trained man power in RE projects.

 

Milestone based progress, provision of penalty/bonus; prescribed time schedule and no cost variation are main features of EPC contract which may be beneficial for RE project.

 

·         CORE is also considering for engaging PMC services specifically in the sections where EPC contract have been awarded. It will ensure execution of works with due control for safety, quality and cost. Tenders for two sections with 456 RKM has already been invited and tenders for three more sections are in pipeline.

 

MAJOR MILESTONES ACHIEVED DURING 2017-18

1.

     Signaling and Telecommunication works in Railway Electrification:

 

 

   

    In RE, Semaphore Signals are required to be replaced by MACLS and mechanical interlocking by Panel Interlocking (PI) and Electronic Interlocking (EI) to make the system immune to Railway Electrification. In many places where MACLS signaling is already existing, the modification are carried out to ward off the unsafe effect of traction return current and induction from 25 kv traction system. The modification such as replacement of existing Line relays, Track relays, Block Instruments etc by AC immunized relays and Block instrument suitable to work in RE area, provision of single rail track circuits etc. are undertaken. In regards to communication system,  additional circuits of Traction Power Control (TPC), Supervisory Control and Data acquisition System (SCADA) are provided at each station, SP, SSP and TSS location.  The overhead communication is replaced by 6 Quad cables.

Details of  Signaling system while resorting to modification / augmentation:

 

 

While modifying/ augmenting the existing Signaling system, the latest guidelines issued by Railway Board are followed for ensuring reliability of signaling equipments installed on the Zonal Railways. Electronic Interlocking, Metal to Metal/Metal to Carbon PI, Digital  Axle Counter Interlocking (SSDAC/MSDAC), LED signals, Integrated Power Supply  systems (IPS),  Block proving by Axle Counter (BPAC) ,  Universal fail safe Block Interface (UFSBI ), Data loggers are provided. On stations where signaling assets are already due for replacement is being undertaken to have better reliability and maintainability. Some of important works carried out as a part of RE in the last few years are detailed below:-

 

 

·         In Rohtak-Bhatinda section 05 stations have been provided Panel Interlocking.

 

 

·         In Meerut- Saharanpur section 08 stations have been provided with Electronic Interlocking.

 

·         In Gondia- Ballarshah section 13 stations have been provided with Electronic Interlocking.

 

·         56 no. Of Block proving by Axle counter (BPAC) and 88 no of Universal Fail Safe Block Interface (UFSBI) are provided on different section

 

·         282no. IPS of latest specification has been commissioned so far at various stations & LC gates.

 

·         Networked Data Logger systems have been provided for real time recording & monitoring of all events of signaling equipments for preventive & predictive maintenance of signaling gears.

 

 

 Telecommunication:

 

Wherever overhead communication exists, induction voltage is produced due parallelism with 25 kv AC which makes circuit noisy on copper cable and unsafe for the staff. Further with the introduction of RE, there is need or additional control circuit such as TPC, TLC, SCADA, etc. To facilitate the above, existing overhead lines are replaced by provision of OFC and 6 Quad cables. In many places, wherever   OFC and 6 Quad cables exist, they are checked for their reliability and identification of higher Earth resistance, low insulation etc. is done and are suitably replaced / attended to ensure interruption free reliable communication.

 

Important features of Telecommunication system being provided as part of RE work:

  -

Old non – jelly filled 4 Quad cable are replaced by new 6 Quad cables to improve reliability.

  -

SDH and Ethernet OFC equipment are provided for augmenting the channel capacity to provide additional circuit by integrating these equipments with Network Monitoring System.

  -

Latest Electronic Digital Exchanges have been provided at RE offices and Sub- divisional HQ offices for vital communication amongst senior supervisors with HQs and stations.

  -

For administrative communication and monitoring of progress of various projects, CUG mobile facility has been extended to all officers and supervisors. In addition to this, video conferencing between Secunderabad, Chennai, Bhubaneswar, New Jalpaigudi projets with CORE have been provided.
