The main railway dream project in Tamil Nadu, the Chennai-Egmore-Kanyakumari double rail project, started in 1998, has now been completed up to Madurai and the train service has also started.
Project works are delayed
In the next phase, construction of double track with electrification is underway between Madurai – Tirunelveli – Nagercoil – Kanyakumari. These works are scheduled to be completed by March 2022.
But due to various reasons like corona virus, financial crisis, delay in land acquisition, these projects got delayed.
Currently, the double track work has been completed till Tirunelveli.
130 kmph, speed
Regarding this, Southern Railway officials said:
The Chennai-Kanyakumari double track project will be completed by this year. 
With this, six service trains can be added to southern districts.
Since most of them are new lines, upgrading the ‘signals’ will allow the existing express trains to run at a speed of 130 kmph.
Thus they said.
