Poonamallee–Vadapalani metro: your guide

The first Phase 2 stretch of Chennai Metro is now carrying passengers. Trains on the Yellow Line (Corridor 4) run between Poonamallee Bypass and Vadapalani, about 15 km on an elevated viaduct, and the end-to-end fare is Rs 40. Commercial service began at 4 pm on Sunday 11 October 2026, a few hours after Prime Minister Narendra Modi and Chief Minister C. Joseph Vijay rode the line, according to DT Next and the Prime Minister’s Office.

The line is not yet running a full day like Phase 1, and six stations along the way are still shut. Here is what a commuter from Poonamallee, Porur or Valasaravakkam needs to know before switching from the bus or the bike.

The 11 stations that are open

Trains stop at these stations, west to east:

Poonamallee Bypass
Poonamallee Bus Stand
Poonamallee Government Hospital
Karayanchavadi
Kumananchavadi
Kattupakkam
Iyyappanthangal
Thelliyaragaram
Porur Bypass
Porur Junction
Vadapalani

Between Porur Junction and Vadapalani the train runs through without stopping. The stations at Alapakkam, Karambakkam, Valasaravakkam, Alwarthirunagar, Saligramam and the one near AVM (Avichi School) are still being finished, Swarajya reported. Residents of those areas will have to board at Porur Junction or Vadapalani for now.

The PMO said the project cost about Rs 4,900 crore. It includes a 3.7 km double-decker section, where the Corridor 5 viaduct will run on the same structure, and signalling built for driverless running. For now each train still carries two operators. DT Next reported that fully unattended operation is expected around mid-2027, once testing and safety certification are done.

Timings and frequency

For now the new line runs shorter hours than the older Blue and Green lines, which work from 5 am to midnight.

Day	Hours	Train every
Mon to Sat, peak (8 to 11 am, 5 to 8 pm)	7 am to 9 pm	10 minutes
Mon to Sat, other hours	7 am to 9 pm	15 minutes
Sundays and public holidays	7 am to 9 pm	15 minutes

The last trains leave Poonamallee Bypass and Vadapalani at 9 pm. If you work late in Guindy or T. Nagar and live past Porur, you will still need a bus or cab home at night. CMRL updated its first and last train timings sheet on 13 October 2026, two days after opening, so check the current PDF before you plan around a specific train.

Fares and how to pay less

DT Next reported that fares on this stretch run from Rs 10 to Rs 40:

Rs 10 for the shortest hop, such as Poonamallee Bypass to Poonamallee Bus Stand
Rs 20 to stations such as Poonamallee GH, Karayanchavadi, Kumananchavadi and Kattupakkam
Rs 30 to Iyyappanthangal and the stations towards Porur
Rs 40 for the full trip from Poonamallee Bypass to Vadapalani

The official CMRL fare table was revised on 9 October 2026 and comes as a PDF, along with a separate chart of the 20% discounted fares. To get that discount, use a stored value product rather than a single paper ticket. The CMRL app’s Store Value Pass starts with a Rs 50 deposit and takes 20% off every journey. The Singara Chennai (NCMC) card also gets the discounted fare. Single-journey QR tickets are sold at station counters and machines, on WhatsApp and through payment apps.

Changing to Phase 1 at Vadapalani

Vadapalani is where the new line meets the Green Line, which has run between Chennai Central and St. Thomas Mount since 2015. Commuters walk between the two stations on an L-shaped skywalk, according to a summary of the launch. From the Green Line you can reach Koyambedu, Anna Nagar, Egmore and Central to the north, or Ashok Nagar, Alandur and St. Thomas Mount to the south. At Alandur you can change again for the Blue Line to the airport and Guindy.

A trip from Poonamallee to Guindy therefore means two trains and one interchange. Before this, the same journey meant a long bus ride on Mount-Poonamallee Road, where traffic piles up around Porur and Ramapuram.

First-week numbers and what to expect next

On the first afternoon, 25,474 people rode the line within five hours, DT Next reported. The citywide network was already busy before this stretch opened: CMRL logged just over 1 crore passenger trips in September 2026, its third straight month above that mark, DT Next reported.

Two changes are expected on this stretch. The six closed stations should open once construction is complete, and the 7 am to 9 pm hours may get longer. CMRL has not given dates for either in anything published so far. For parking at the new stations, CMRL posted fresh parking facility and tariff documents on its latest updates page this month.
