The line is identified as T2A. You can find this designation on metro maps, signs in passageways, platform information boards, and transport apps.

This metro line runs through Hanoi (Vietnam). Metro lines typically connect several parts of the city — from residential neighbourhoods to business districts and the city centre. To find out whether this line suits your journey, open the metro map and check the station locations relative to your destination. Sometimes one transfer is more convenient than searching for a direct route.

The average interval between trains is 10. During peak hours trains run considerably more frequently, while late in the evening and at weekends the interval is typically longer.

Providing your station, direction of travel, and the time of your journey will help them handle your enquiry more quickly.

This line is part of the «Hanoi Metro» network. Within a single transport network, the same fare rules, ticketing, and transfer policies typically apply.

Operating hours for this line: Mo-Su 05:00-23:00. The times of the first and last trains may differ on weekdays, weekends, and public holidays.

On metro maps, this line is shown in #00C000. Colour coding is the primary navigation aid in metro systems — it helps you quickly identify the right direction on signs, maps, and information boards. When making transfers, always pay attention to the line colour to avoid confusing platforms or directions.

No. A circular line runs in a closed loop with no terminal stations, which makes it particularly convenient for transfers. Regular lines run between two terminal stations in both directions. In either case, always check the final destination of the train on the platform board to make sure you are boarding in the right direction.
