CHENNAI (Metro Rail News): Switching between two stretches — Corridor 4 and Corridor 5 — will be seamless when commuters travel in the Metro train under the Phase II project in around four years, since they will run parallel to each other for five kilometres. This will primarily benefit residents of Poonamallee, Kattupakkam, Karambakkam, Porur, and surrounding areas who wish to go to any northern or southern part of the city.

The construction of the Phase II project in the city has begun, with three corridors — Madhavaram to SIPCOT (Corridor 3), Light House to Poonamallee (Corridor 4) and Madhavaram to Shollinganallur (Corridor 5) — costing 61,843 crores with funding from the State and Union governments as well as international banks.

It’s critical to have well-planned transit stations in such a large public transportation system so that commuters don’t get lost switching trains. Corridor 3 and Corridor 5 intersect in this project in Shollinganallur and Madhavaram, while Corridor 3 and Corridor 5 intersect at Thirumayilai. However, Corridors 4 and 5 each feature four transit stations because the alignment goes for nearly 5 kilometres in the same direction, with one corridor running above the other.

The double-decker line would contain four stations built on two levels, according to authorities from Chennai Metro Rail Ltd. (CMRL) – Alwarthirunagar, Valasaravakkam, Karambakkam, and Alapakkam. While Corridor 4 will be built on the first level, at a height of 13.5 metres above the ground, Corridor 5 will be elevated to a height of 21 metres.

According to the official “The work has been going on for a few months now and after soil testing, the contractor has been executing pile work after which pillars will be raised. These two stretches will run with shared pillars for 5 km. And, there will be common concourse (ticketing level) and two different platforms.”

The benefit is that commuters from Porur may get to destinations like Adyar, Mylapore, Shollinganallur, Taramani, Madhavaram, Retteri, Majambakkam, and CMBT in a short period of time.
