Aegap, the stations and overall system was built with the notion of keeping the service fit to expand as added lines continue to create more demand and congestion within the Metro itself.
For this aim the stations were designed to be able to expand the train sets from 3 cars (as today and while in commercial service they will be set in such configuration) to as many as doubled that number to 6. That takes care of demand growth while keeping the need to expand infrastructure in check for a good longtime.
If you also notice the height of the ceilings in all stations is really extreme compared to other systems in use today, which takes care of humidity and air quality issues; as well as providing room for future enhancements to the system. The air flow dynamics is greatly impacted when you provide a larger area for the same to flow free of obstructions, saving money in AC ventilation and exhausting any foul odors and dangerous concentrations of fumes in the stations themselves in case of fires away from users.
An air quality monitoring system is installed and can provide an early warning alarm should any evacuation be required for safety issues.
The trials actually confirmed that ridership projections are within the margin expected during the construction of the system. Maybe even a bit over but that's understandable given the nature of the FREE rides relying on curiosity.
On a note: Just to shut the mouth of some "experts", the Metro didn't cause a major blackout in the Capital as dully reported by media and word of mouth. The actual energy used to make the trial runs is below any expectations and projections made before hand.
