A metro or railway station is public by design, but behind the platforms sit operational areas, control rooms, depots and technical spaces that must be tightly controlled. The people who need access there — engineers, contractors, vendors, officials — are a very different flow from the travelling public.
Two worlds in one station
Passengers move freely through the public concourse; operational access is the opposite — restricted, accountable and safety-critical. Visitor management is about that second world: who entered the signalling room, the depot or the plant space, and whether they were cleared.
What operational access needs
- Identity verification for contractors and engineers.
- Access scope by area — a cleaner is not a signalling technician.
- Restricted Visitor screening and a complete log.
- Offline-capable checks where connectivity is patchy underground or trackside.
Safety and accountability
In safety-critical infrastructure, being able to prove exactly who accessed an operational area, and when, is both a security control and an audit requirement — the same discipline as data centres and energy sites.
Certopact for transit operators
Certopact Access manages operational-area entry with screening and a searchable log, and Certopact Entry verifies identity online or offline. This complements transit authorities' own security requirements.
