Chennai Metro Corridor 4 Parking: Where You Can Park, What It Costs, and What Buyers Should Check
CMRL's parking list effective 11 October 2026 shows car parking at only four of the eleven Corridor 4 stations between Poonamallee Bypass and Vadapalani, and none at Porur Bypass or Poonamallee Bus Stand. Rates, EV and night rules, and checks for flat buyers along the line.
At 4pm on October 11, 2026, the first passenger trains ran on Chennai Metro's Corridor 4 between Poonamallee Bypass and Vadapalani, eleven elevated stations over about 15 km. For families looking at flats in Poonamallee, Karayanchavadi, Kattupakkam, Iyappanthangal or Porur, the line changes a daily question from "how long is the drive" to "where do I leave the vehicle". CMRL answered part of that question with a station-by-station list, effective the same date, of where two-wheelers and cars can be parked.
This guide uses CMRL's own documents to show which Corridor 4 stations offer parking, what it costs, and what a buyer should check before counting on a park-and-ride commute.
The short answer. According to CMRL's parking facilities list effective 11-10-2026, only four of the eleven Corridor 4 stations list car parking: Poonamallee Bypass, Poonamallee Government Hospital, Kattupakkam and Thelliyaragaram. Two stations, Poonamallee Bus Stand and Porur Bypass, list no parking at all. At the new stations, a metro traveller using a CMRL or NCMC card pays Rs 15 to park a two-wheeler for 6 to 12 hours, or Rs 30 for a car, under the CMRL parking tariff. The trade-off: parking is cheap where it exists, but the nearest station to a flat may not be the one with space for your vehicle.
What opened on Corridor 4, and when do trains run?
CMRL's press release of 10.10.2026 announced regular passenger services from 11th October 2026 on Corridor 4 of Phase 2, covering 11 elevated stations over approximately 15 km from Poonamallee Bypass Metro to Vadapalani Metro. The stations are Poonamallee Bypass, Poonamallee Bus Stand, Poonamallee Government Hospital, Karayanchavadi, Kumananchavadi, Kattupakkam, Iyappanthangal, Thelliyaragaram, Porur Bypass, Porur Junction and Vadapalani.
Services initially ran from 7am to 9pm. A second release dated 21.10.2026 said that, based on commuter feedback, the start time would be advanced to 6:00 am with effect from 23rd October 2026. From that date services run from 6am to 9pm in both directions. On Monday to Saturday, trains run every 10 minutes in the peak windows of 08:00 to 11:00 and 17:00 to 20:00, and every 15 minutes otherwise. On Sundays and holidays there is no peak-hour service and trains run every 15 minutes. The last train departs at 9pm from both terminals.
PropNewz covered the feeder bus link that CMRL launched at Porur Bypass in its earlier report on the Porur Bypass Metro Connect service.
Which Corridor 4 stations have parking?
CMRL's list, headed "Parking facilities available @ station w.e.f. 11-10-2026", gives a simple available or not available entry for two-wheelers and four-wheelers at each station. For Corridor 4, listed there as Line 04, here is what it shows for five stations buyers in the western suburbs are most likely to compare:
| Station | Two-wheeler parking | Four-wheeler parking |
|---|---|---|
| Poonamallee Bypass | Available | Available |
| Poonamallee Bus Stand | No parking facility | No parking facility |
| Kattupakkam | Available | Available |
| Iyappanthangal | Available | No parking facility |
| Porur Bypass | No parking facility | No parking facility |
For the remaining stations on the line, the list shows Poonamallee Government Hospital and Thelliyaragaram with both two-wheeler and four-wheeler parking, Karayanchavadi, Kumananchavadi and Porur Junction with two-wheeler parking only. The Vadapalani entry, listed under Line 02, shows two-wheeler parking only. The tariff sheet confirms the two-wheeler-only status for Karayanchavadi, Kumananchavadi, Iyyapanthangal and Porur Junction.
What does parking cost at the new stations?
CMRL's tariff sheet groups stations by rate card. The new Corridor 4 stations with parking, from Poonamallee Bypass to Porur Junction, fall in a group of 24 stations whose tariff applies with effect from 1.2.2025. Each rate card distinguishes between "non-commuters / irregular commuters" and "metro travelers used CMRL/NCMC card in AG for the day", meaning those who passed the automatic gates with a CMRL or NCMC card that day.
For that 24-station group, the sheet lists these rates. A two-wheeler pays Rs 25 for 0 to 6 hours, Rs 40 for 6 to 12 hours and Rs 55 for more than 12 hours if the rider is not a metro traveller, against Rs 10, Rs 15 and Rs 20 for a metro traveller. A car pays Rs 40, Rs 50 and Rs 65 as a non-commuter, against Rs 20, Rs 30 and Rs 40 for a metro traveller. Beyond service hours, the charge is Rs 70 or Rs 50 for a two-wheeler and Rs 125 or Rs 100 for a car.
As a rough illustration, a commuter who parks a car for 6 to 12 hours at Rs 30 on 22 working days would pay Rs 660 in a month, and a two-wheeler rider at Rs 15 would pay Rs 330. These are arithmetic examples from the published rates, not CMRL figures, and actual spend depends on hours parked and the rates in force.
How do these rates compare with older stations on Lines 1 and 2?
The new stations are not the cheapest on the network. CMRL's tariff sheet lists a separate group of 20 stations, also effective 01.02.2025, that includes Koyambedu, Arumbakkam, Ekkattuthangal, Teynampet, Saidapet, Shenoy Nagar and Anna Nagar East. In that group, a metro traveller pays the same Rs 10 and Rs 15 for a two-wheeler and Rs 20 and Rs 30 for a car for up to 6 hours and 6 to 12 hours, but a non-commuter pays less than at the new stations: Rs 20 and Rs 30 for a two-wheeler and Rs 30 and Rs 40 for a car.
Chennai Central has its own slabs. There, a car parked by a metro traveller costs Rs 30 for up to 4 hours, Rs 60 for 4 to 8 hours, Rs 120 for 8 to 12 hours and Rs 200 for more than 12 hours within revenue hours. For a buyer comparing a western-suburb flat on Corridor 4 with one nearer an older line, the practical point is that the metro-traveller rates for a typical working day are similar across the two main groups, while Chennai Central is far more expensive for cars.
What about parking at the Vadapalani end?
Vadapalani has its own rate card, effective 1.5.2024. The facility list does not give a separate Line 04 entry for Vadapalani; the Vadapalani station it lists, under Line 02, shows two-wheeler parking only. A metro traveller pays Rs 10 for up to 3 hours, Rs 15 for up to 6 hours, Rs 20 for 6 to 12 hours and Rs 30 for more than 12 hours. A non-commuter pays considerably more, from Rs 40 for up to 3 hours to Rs 160 for more than 12 hours. So a buyer who plans to drive to the Vadapalani end of the line should not assume a car can be parked there without checking first.
What special rules apply to EVs and night parking?
The tariff sheet carries four notes. Vehicles of differently abled persons park free during revenue hours only. E-vehicle parking is free "applicable only for CMRL Commuters during Revenue hours". The commuter fare is not applicable for halt days and is calculated only for the exit day. Night halt hours are listed as 01:00 to 04:30.
For a household that owns an electric scooter or car and plans to commute by metro every day, the free EV parking for commuters during revenue hours is a meaningful saving. It is worth confirming at the station counter how CMRL applies it in practice, since the sheet does not describe the verification process.
How should a buyer use this when choosing a flat?
Treat the walk or ride to the right station, not the nearest one, as the real commute. A flat that is closest to Porur Bypass or Poonamallee Bus Stand, both listed with no parking, may suit someone who walks or uses a feeder, but not someone who needs to park. A flat near Kattupakkam or Thelliyaragaram, which list car parking, may suit a driver better even if it is a little farther from the line.
Remember also that the list and the tariff are CMRL's current documents and can change, and that availability on the list does not mean a guaranteed slot at peak hours. For a wider look at what a metro construction milestone does and does not mean for buyers, see PropNewz's report on Chennai Metro Corridor 5 progress on the OMR side.
A seven-point checklist for buyers along Corridor 4:
- Identify the two or three stations within reach of the flat, not just the nearest one.
- Check CMRL's parking facilities list for each of those stations, separately for two-wheelers and cars.
- Note which rate card applies, since Vadapalani and some older stations use different tariffs.
- Work out a monthly parking cost from the published rates for your expected hours.
- Confirm first and last train times against your working hours: currently 6am to 9pm.
- If you own an EV, ask at the station how free commuter parking during revenue hours is applied.
- Visit at peak hour on a weekday to see whether parking actually has space.
