Rail
Greater Aomori has a network of railway lines. Main rail terminals in the area include, Aomori Station, Shin-Aomori Station, and Okutsugaru-Imabetsu Station.

High speed rail
JR East and JR Hokkaido operate high-speed trains on the Tōhoku-Hokkaido Shinkansen line. Shin-Aomori Station acts as the Shinkansen terminal station, though the two lines are physically joined, and many trains offer through service. This station is connected to Aomori Station in central Aomori by the Ōu Main Line. The smaller high-speed station, Okutsugaru-Imabetsu Station is also within Greater Aomori.

Commuter rail
Both JR East and private lines connect Aomori and its suburbs. The Aoimori Railway Line is operated by the Aoimori Railway Company, a "third-sector" publicly and privately owned company. It connects Aomori Station and central Aomori to Hiranai in Greater Aomori and continues towards Noheji, Misawa, and Hachinohe. The Tsugaru and Ōu lines operated by JR East have termini at Aomori Station. The Ōu Main Line connects Aomori to Hirosaki and points to the south, while the Tsugaru Line connects Aomori Station and Minmaya Station in the town of Sotogahama on the northern tip of the Tsugaru Peninsula.
