Commissioned stations are built as paid and unpaid areas separated by AFC gates. Expect X-ray and DFMD security, lifts to concourse and platform, escalators on many levels, CCTV, PA, and a customer-care window.
Toilets and drinking water are provided where the station is fully commissioned. Retail may appear later. Do not block lift doors with tourist groups — use stairs if you can.
