The KL CAT ERL Station is located within the KL Sentral Rail terminal which also services the KTMB Intercity, KTMB Commuter and PUTRA LRT systems.

The main station space for the ERL consists of two large separated spaces, namely the Arrival and Departure Halls. Each concourse space is 97m long, 47m wide and up to 17m high. At 7.3m above the Concourse Level, the PUTRA LRT viaduct runs across the Concourse space.

Computer fluid dynamics (CFD) modeling was done to study the stratification effects on cooling load, appropriate air distribution strategy and the effect of movement of the PUTRA LRT train through the concourse.

The CFD modeling utilizing ESP and Microflo softwares was done in house over a period of two months.

Smoke spill design for the Concourse and Platform areas were based on fire size analysis.
For the platform area, due to the complexity of the various fire scenarios, a Cause and Effect Matrix Chart was devised to document the design requirements. The Chart was referred to extensively during programming of the fire systems for testing and commissioning.

Instead of the usual two speed fans or reversible fans for smoke spill at the Platform during fire mode, by matching fan curves, appropriate fans were selected such that the flow rates during fire mode could be achieved by just switching on the standby fans in addition to the duty fans during fire mode. This resulted in substantial costs savings.

Special attention had to be paid to routing and location of services in view of the large volume spaces and constraints of working entirely within the core and shell spaces allocated.

All services had to be interfaced with the KL Sentral infrastructure and provisions.
