The U3 platform of the station is under Spichernstraße; the U9 platform is under Bundesallee. Both have exits at each end of the platform. The station is equipped with escalators but not with lifts and is therefore not completely accessible to the disabled.
U9
The U9 portion of the station, designed by Bruno Grimmek, is standard for this line; it was one of the first built. Like all stations on the line, it has a centre platform wide. Exits at the two ends of the platform lead to Joachimsthaler Straße in the north, at the south end a mezzanine and passageways connect to the U3. When the station opened, the walls were pale blue and the hexagonal columns on the platform dark blue. Grey tiles with pink and white patterns and dark blue columns were used in the mezzanine areas. Although the station was a terminus until 1971, it did not have a turning area. Trains terminated at the platform, and changed tracks before entering it. The platform space was completely renovated in 1986/87: both walls and columns were clad in white tiles, with a pattern of coloured tiles on the walls. The design by Gabriele Stierl is intended to represent the visualisation of a piece of music for an ensemble of 12 instruments, in homage to the nearby Berlin State School of Music and the Performing Arts. The "butterfly ceiling" which was also typical of the stations on this line was replaced with panels, with a relief line in yellow running down the centre as a sharpcolour contrast.
U3
As there had not been a station on the A II/B II line at the interchange point, the Nürnberger Platz station, located only one or two hundred metres to the north, was replaced with the new Spichernstraße station, while the new Augsburger Straße station was opened in the northeast. To facilitate transfers to the new G line, the U3 section of Spichernstraße station was built with side platforms rather than a centre platform as at the old station. Construction was relatively simple since there was a turning area for the Nürnberger Platz station at the location; trains were routed over the ancillary tracks and the new platforms constructed on the site of the former main tracks. The station has exits at both ends. A passenger tunnel under the tracks connects the two platforms; the connection to the U9 is at the south end of the station. This part of the station still has pale blue tiled walls; the mezzanine and the passage leading to the U9 have sand-coloured tiles.
