SilverLine on the wings of fire of leap and hope
The ambitious project to make history in the development of transport facilities in God's own country is now on the wings of fire of leap and hope. The SilverLine; the semi high-speed rail corridor, a sustainable development project envisaged to address the inadequacies of public transport in the state, has seen high hopes as it obtained requisite clearances from NITI AAYOG, Railway Board and Department of Expenditure for posing the project for Multilateral/Bilateral funding. It is expected that the project will give an impetus to the economic growth of the state in post-Covid Kerala.
The pre-investment and fundraising activities of the mega project are already underway. The semi-high speed rail corridor will connect the capital city of the state, Thiruvananthapuram with the northernmost district Kasaragod in less than four hours.
SilverLine is envisaged as a Green Project, which will bring employment to about 50,000 people directly and indirectly during its construction phase and to around ten thousand people at the completion of the project.  Concept models and designs are being prepared for the buildings, depots, rolling stocks and various structures related to the alignment. Scientific soil testing has already been carried out at 127 locations along the proposed alignment. Additional Soil investigation of 200 bore holes planned for the location of various important structure like, River bridge, Viaduct, Tunnel, ROBs, ROR and retaining wall etc.

The detailed project report (DPR) and alignment of the SilverLine project approved by the State Government along with the recommendations of the Zonal Railway and the explanation of the KRDCL were sent to the Railway Board for approval on 17 June 2020. It is expected that final approval for the project, which has already got the In-Principle approval by the Railway Board, will be available soon. Now SilverLine Project is awaiting the administrative Sanction of the new state cabinet for land acquisition.

The following preliminary/preparatory works are also in progress
* Review of DPR by Rail India Technical and Economic Services Limited (RITES).
* Preparation of draft tender for Project Management Consultancy Contract, draft EPC tender document and tender packages as per funding requirement of various financing agencies like MDA/BA, ADB, AIIB, KfW and JICA

* Preparation of SOD for SilverLIne.
* Preparation of Concept Design for the various structures coming along the SilverLine alignment.
*Cadastral survey of the alignment duly collecting the Field Measurement Book from Survey Director, GOK and digitizing the same through an agency KSREC.
* CRZ Mapping of the alignment entrusted to NCSCM/Chennai and for processing for CRZ clearance.
* Comprehensive EIA study is being planned in addition to the Rapid EIA study done along the alignment.
* Station concept plans are being prepared for all stations.
* Hydrological survey being carried out for all major river along the alignment.
* Development of Land acquisition software/portal (Similar to Bhoomirashi, developed by NHAI) jointly with Land Revenue Commissioner, Kerala &NIC as per the RFCTLARR ACT 2013 of Kerala.
HUDCO sanctions loan of Rs 3,000 crores @8% interest rate
By pouring energy into the land acquisition procedures, Housing and Urban Development Corporation (HUDCO) has sanctioned a loan of Rs 3,000 crores for the Thiruvananthapuram-Kasaragod semi-high speed rail corridor project. The loan was sanctioned at an interest rate of 8% per year for the first phase of land acquisition of SilverLine from Kochuveli to Chengannur. Kerala Rail Development Corporation Limited (KRDCL), a joint venture company of the Central and State Government entitled to the development of railway infrastructure in the State, is implementing the project.

The expected cost of acquiring 320 hectares of land from Kochuveli to Chengannur is Rs 3,750 crore. HUDCO has demanded a guarantee from the state government to repay the loan and interest in annual instalments on the loan sanctioned and that there should be a provision in the state budget for the same. 

In addition to HUDCO, discussions are underway with Kerala Infrastructure Investment Fund Board (KIIFB) and Indian Railway Finance Corporation (IRFC) for the Rs 13,265 crores towards land acquisition cost of the SilverLine project. . International financial institutions like ADB, JICA, AIIB and KFW are being approached through the Union Ministry of Finance with a view of raising Rs 33,700 crore multilateral fund for the project.

Green signal for SilverLine's loan mobilization

National Institution for Transforming India (NITI Aayog),  Department of Expenditure of Ministry of Finance and Railway board have reccomended the project for raising multilateral loan from international financial institution.
The NITI Aayog, the Expenditure Department and Railway board have examined and extended their support to the multilateral loan mobilization plan submitted by KRDCL and made a recommendation to the Department of Economic affairs of the Union Ministry of Finance.
The NITI Aayog had sought clarification on the implementation and practicality of the scheme in the initial phase regarding the loan from the Asian Development Bank (ADB). KRDCL had then commissioned the Rail India Technical and Economic Services Limited (RITES), an engineering consultancy with experience in the field of transport infrastructure development under the Ministry of Railways, to study the same and responded to NITI Aayog based on the report of RITES. After evaluating the clarifications submitted by KRDCL, the NITI Aayog on April 5 recommended raising multilateral loan for SilverLine.
KRDCL begins steps to revise estimate of Sabari
The much-anticipated railway project of marking the famous pilgrimage site of Sabarimala on the railway map of the country has got a fresh lease of life and is nearing realization. The Sabari Railway project is being revitalized after Kerala government has agreed the demand of Railways to bear half of the project cost. Kerala Rail Development Corporation Limited (K-Rail), a joint venture company of the Central and State Governments, has started the work of revising the estimate of the Angamaly-Erumeli Sabari railway line.
K-Rail has invited tenders for conducting Light Detecion and Range (LiDAR) Survey at Ramapuram-Erumelistrech for a distance of 40 km. The aerial remote sensing survey is being carried out by a small aircraft to collect accurate and precise information of the land through which the rail corridor passes. A similar aerial survey was carried out by the KRDCL, for the proposed Thiruvananthapuram-Kasaragod semi-high speed rail project.
The revision of the project estimate is due to the fact that it is not possible to proceed with the project as estimated years ago.The State Cabinet had already decided to make available 50 percent of the estimate to Railways from KIIFB. As per the plan envisaged years ago, the initial estimate for the Sabari Railway was Rs. 550 crore. With the delay in realization, the estimate rose to Rs 1,234 crore in 2005 and Rs 1,566 crore in 2011. According to the latest estimate, the project cost was expected to be Rs.2815.62 crore. About 470.77 hectares of land will be acquired for the 116 km long Sabari Railway which will pass through Ernakulam, Idukki, Kottayam and Pathanamthitta districts.
