Kuala Lumpur Sentral Station is an integrated transportation hub that caters for various modes of rail transport. It includes KTMB intercity and commuter services, Putra LRT services and Express Rail Link (ERL) services. The station is the integral part of the overall KL Sentral development.

Crowning the complex is a series of Hyperbolic Paraboloid (HP) shell roofs flanked by waved roofs to each side. The HP shell roofs together with the suspended domes and granite flooring patterns poetically expresses the fusion of modern technology with Islamic architecture. The features also enrich the high-tech structural steelworks of the station. Spanning the East-West axis of the station, the sweeping waved roofs reflect the directional flow and motion of the railway tracks below.

The waved roofs are supported by steel columns branching out at a high level into radiating smaller members. These structural expressions and the distinctive form of the HP shell roofs emulate the KLIA roofing system, creating a symbolic gesture for the station being an extension of the airport: the city air terminal for Kuala Lumpur.
