The suburban railway part of the station at the north side is listed as Barmbek (S-Bahn), No.

[5] On 11 April 1895, the first new built electric tram line was opened from Barmbeker Zoll (Barmbek customs facilities) to Ohlsdorf Cemetery,[6] and on 6 December 1906, the Hamburg-Altonaer Stadt- und Vortbahn (City and suburban railway) — since 1934 abbreviated Hamburg S-Bahn — opened the double track line Ohlsdorf – Blankenese, including Barmbek station.

[7] Planned as an electric railway with overhead lines, the trains were first steam powered, because of difficulties concerning the construction of the electrical installations and a delay delivering the engines.

[8] In 1912, the Hamburger Hochbahn opened first part of the Hamburg U-Bahn circle line from Barmbek station via Mundsburg to central station.

In the westside entrance level are some shops, escalators and lifts to the platforms and to the bus station.
