(a) to (c):  Chengalpattu is an existing station on Chennai-Villupuram route. Mamallapuram is about 27 km away from Chengalpattu Jn. which serves as the transportation hub for the town & nearby region.

A  survey  of  Chengalpattu  -  Mamallapuram  New  line  was  carried  out  in 2014.  According to the survey the project has low traffic projections.

The sanctioning of project requires consultation with various stake-holders including State Governments and necessary approvals viz. appraisal of NITI Aayog, Ministry of Finance etc. As sanctioning of projects is a continuous and dynamic process, exact timelines cannot be fixed.

Execution  of  important  infrastructure  projects  falling  fully/partly  in  the State of Tamil Nadu are held up due to delay in land acquisition. Status of land acquisition in Tamil Nadu is as under:

| Total Land required for Projects in Tamil Nadu   | 4,326 ha       |

| Land Acquired                                    | 1,052 ha (24%) |
| Balance Land to be acquired                      | 3,274 ha (76%) |

Support of the Government of Tamil Nadu is needed to expedite the land acquisition.

## Details of some major projects which are delayed due to land acquisition are as under:-

Further, Rameshwaram - Dhanushkodi new line (18 km) was sanctioned at a  cost  of    ₹734  Cr.  The  Foundation  Stone  of  the  project  was  laid  on 01.03.2019.  However,  the  project  could  not  be  started  because  the  land acquisition has not been undertaken by the State Govt. of Tamil Nadu.

Government  of  India  is  geared  up  to  execute  projects,  however  success depends upon the support of Government of Tamil Nadu.

Sanction  of  any  railway  project  depends  upon  many  parameters/factors which include the following:

-  Anticipated traffic projections and remunerativeness of the proposed route

-  First and last mile connectivity provided by the project
-  Connection of missing links and providing additional route
-  Augmentation of congested/saturated lines
-  Demands  raised  by  State Governments/Central  Ministries/Public representatives
-  Railway's own operational requirements
-  Socio-economic considerations
-  Overall availability of funds

Completion of Railway project/s depends on various factors which include the following:

-  Land acquisition by State Government
-  Forest clearance
-  Shifting of infringing utilities
-  Statutory clearances from various authorities
-  Geological and topographical conditions of area
-  Law and order situation in the area of project site
-  Number of working months in a year for particular project site etc.

All these factors affect the completion time and cost of the project/s.
