The New Era of Assisted and Unattended Driving

Growing urbanization accelerates the demand for more mobility – and reinforces an unstoppable trend: the shift of transport from road to rail. But it faces a coming shortage of competent drivers. The key to counteract is assisted and unattended driving of trains and trams. Driverless train operation for metro systems is already state-of-the-art. Examples include the automation of subway line 1 in Paris, the subway in Nuremberg, as well as many other new metro lines in the world. But mainline and tram operators plan to increase the capacity, flexibility, and energy efficiency of rail operations using higher levels of automation. It starts with assistance systems that continuously support drivers in their tasks. And continues with a key building block for future train automation – automatic obstacle detection based on a rail perception system. Our Rail Perception System combines sensors and data analytics technologies on vehicles to automatically perceive the surrounding and to trigger actions. Automatic obstacle detection based on the Rail Perception System can assist your drivers in avoiding collisions on the track. Combined with train control and rail infrastructure it enables driverless and unattended train operation (GoA Level 3 and 4).

Your benefits of assisted and unattended train operation:

Lower repair costs and higher availability of your trains by avoiding or reducing damage from accidents

Increased punctuality and flexibility by driverless train operation 

Improved safety and throughput 

More comfort for your passengers by smooth acceleration and braking

How a rail perception system works

Due to the automatic perception of the surrounding, important actions are triggered in combination with train control and rail infrastructure to enable supported and fully automatic unattended driving.

Safer Transportation with Automatic Obstacle Detection

Siemens’ automatic obstacle detection based on the Rail Perception System enables you as a train or tram operator to realize different use cases:
  • Driver assistance: (automatic) train operation with collision avoidance support
  • Driverless depot operation
  • Driverless vehicle stabling and provision
  • Driverless operation on specific sections and on entire lines
