In addition to the list mentioned by you I suggest further Cities/Towns such as Marthandam,Shenkottai,Rajapalayam,Sivakasi,Pollachi,Nagapattinam,Karaikkal,Pondicherry,Tiruppur,Coimbatore,Hosur,Katpadi ,Gummidipoondi and Tiruthani to Start and Terminate Trains.
So necessary PIT LINE have to be provided. The Concerned CITY CORPORATION / Municipality should provide necessary Free Land along the Railway Track near the Station premises in consultation with the District Authority.Morever respective MPs should contribute MP DEVELOPMENT FUND for the Pit Line Project.
Moreover I Personally suggest that 20 % part of the Land in (near by Railway Track)...
more...

the unused Pond / KANMOI / Pool / Reservoir may be utilized for providing the Pit Line and the balance 80% of the Pond/Kanmoi/Pool/Reservoir should be deepened for 1 to 2 meter with protective Wall and so as the existing water carrying capacity of these reservoir s are not decreased.
In Tamilnadu so many Pond/Reservoir have been converted as New Bus Stand by the Cities/Towns. Only One example* Salem City New Bus Stand *.
So i suggest Only 2 Pit Line site ,* for Kovilpatti in Thoothukkudi District and Sivakasi in Virudhunagar District*.
In both towns on the Railway Track near by Reservoir s 20 % of the Land have to be utilized for the Pit Line Project and the balance 80 % of the reservoir should be deepened by 1 to 2 meter.Concerned MPs should be contribute MP DEVELOPMENT FUND for the Pit Line Project for Starting and Terminating Passenger, Express and SF Trains with in Tamilnadu and Long Distance Trains to other States.
