Alandur metro station is an elevated metro station that is part of the Blue Line and the Green Line of the Chennai Metro, and serves as an interchange station between the two lines. The station is one of the two metro stations where the two lines intersect, the other being the Chennai Central metro station. It is the city's first multi-level railway station. It is the only station where passengers from the two corridors can swap the direction of travel.

As the station acts as a transit point for two different corridors of the Chennai Metro, the two lines are constructed at two different levels at the station—the first one serving the line from Guindy towards Officers Training Academy (OTA) and Chennai airport and the second one for the line from St. Thomas Mount towards CMBT. The two levels are being built at 26.55 m and 35.41 m within the station, connected by means of escalators. Each levels will have two access points for entry and exit. A mezzanine floor—an intermediate level between ground floor and level I—is being built to be utilised for maintenance purpose.

A total of eight elevators will function at the station—four connecting the ground floor with level I and another four, along with four escalators, connecting level I with level II. The station will have 10 ticket counters apart from 18 automatic ticket-vending machines (ATVMs).

The station will have four access points on the ground floor—two for entry/exit from the front and two more on the rear. Ticket counters, one at either side of the lobby, are located past the access points. Crossing the lobby, passengers can move on to level I using any of the eight escalators and four lifts.

Level I is the alighting point for those travelling on the Guindy–OTA–Airport route. From this level, there are four escalators and lifts leading to level II, from where passengers bound for the Koyambedu–SIDCO–St. Thomas Mount route can embark.

The station will also have disabled-friendly facilities, including separate escalators and entry ramps.

The station is one of the few in the corridor that will have parking facilities.

A 230-kV receiving substation (RSS) is being built by the Tamil Nadu Electricity Board near the station for CMRL project. TNEB would supply 110 kV power from nearby TNEB substation (being built by TNEB) to the RSS, which will be stepped down to 33 kV and 25 kv by two transformers. The station is one of the three stations in the Chennai Metro Rail network to have a 230-kV receiving sub-station for power supply from the state's electricity grid, the other two being Koyambedu and Chennai Central.
