Automatic Selective
Door Operation

On-train digital technology designed to enhance passenger safety

Ensure the safe operation of passenger doors at short platforms with our Automatic Selective Door Operation solution.

Our Automatic Selective Door Operation (ASDO) solution supports the flexible use of your fleet across peak and off-peak periods, allowing longer trains to be immediately and safely deployed onto services where short passenger platforms are in place, maximising the availability of your rolling stock.


The system automatically combines multiple data sources to identify which doors should not open at each stopping point. An in-cab display provides the driver with confirmation of the train location, the proposed door release pattern and the door interlock status. The driver can override the ASDO interlock pattern or quickly release all doors in an emergency egress condition.


Our ASDO solution is controlled and managed by the operator remotely using our back-office software, eyeTrain Connect. It requires no on-track or station hardware which not only reduces the time and cost required to deploy the system, but it also increases safety for track workers who do not need to be trackside.
