Although there are four platforms at the station, only platforms 1 and 4 are fully functional. There are three tracks that run through the station, with platforms 2 and 3 sharing the middle track that is located in the middle of the station. The middle track is primarily used as a siding, and it leads to the Kowloon Bay MTR depot, located west of Kowloon Bay Station. Platform 2 is the Termination Platform for back-to-depot trains, while Platform 3 is the boarding platform for out-of-depot trains towards Yau Ma Tei.
The platform screen doors of the third track served as prototypes in 2001 when MTR started to test the feasibility of installing these doors in stations throughout its system.
