An airport checkpoint is only one visible point in a continental system. People, goods, energy, and information move through networks whose security depends on cooperation across public agencies and private operators.
This page explains the archived exhibit’s transportation network. Use TSA.gov for current surface-transportation programs.
Six connected modes
TSA works with operators, local authorities, law enforcement, other federal agencies, workers, and the public. Different modes require different balances of regulation, assessment, training, technology, and partnership.
Commercial airports combine passenger and baggage screening, credentialing, secure areas, cargo controls, intelligence, airport law enforcement, and layers of technology. The challenge is to protect movement while serving millions of travelers.
Open stations, dense ridership, frequent stops, and local operations make rail security different from airport screening. Preparedness relies heavily on visible presence, training, information sharing, inspection, and coordinated response.
Intercity buses, commercial motor vehicles, bridges, tunnels, and highway infrastructure move people and commerce across a system too broad for a single checkpoint model.
Railroads carry essential goods and hazardous materials across long distances and through cities. Security planning considers routes, facilities, worker awareness, information, custody, and emergency coordination.
Pipelines move energy through distributed physical and digital infrastructure. Resilience requires attention to operations, cybersecurity, control systems, physical facilities, and coordination among owners and public agencies.
Ports connect ships, terminals, trucks, rail, workers, cargo, and international trade. Multiple authorities and industries share responsibility across the water’s edge.
Layered security
No technology or procedure can carry the mission alone. Intelligence changes what people look for. Training turns information into action. Design changes how spaces behave. Inspection verifies practice. Partnerships make a local response part of a national network.
Technology gallery
Can a system identify risk accurately, respect the person moving through it, support the workforce using it, and adapt when conditions change?
Screening tools are meaningful only as part of a process: requirements, procurement, testing, training, deployment, maintenance, and continual evaluation.

The purpose of the system is not restriction for its own sake. Transportation connects families, communities, work, trade, emergency response, and national life. The mission is to protect that movement while allowing it to continue.
