The station has two side platforms and four tracks with no open crossovers or crossunders. Evidence of a sealed-up crossunder is present at the north end. The local tracks are at a slightly higher level than the express tracks; it is believed that this was to aid deceleration and acceleration of local trains entering and leaving the station.
The station was renovated in 1994 by in-house contract. The 1994 artwork is entitled Platform Diving by Deborah Brown; it interprets the question "What kind of subway would sea creatures use?"
