As part of the mindbox accelerator of Deutsche Bahn, VISCOPIC was selected by a top-class jury, including the DB board as a partner, to find a solution to the problem of knowledge transfer caused by demographic change. In cooperation with the technical qualification of DB Netz AG, workshops with department heads, trainers and training participants were carried out and technicians were accompanied in the field. The data collected was then analyzed, the current processes got mapped and use-cases were identified. The result was 118 pain points, which we prioritized together with DB Netz.
Based on this, 10 areas with optimization potential were identified and finally the transfer of knowledge in the technical qualification was selected. The biggest challenge here is that more and more experts from DB Netz AG are retiring and knowledge transfer to the new generation of technicians is currently difficult to scale. Another challenge was that it is currently difficult to train new employees in real facilities, since the train has a lot of different facilities in the field and only a limited number of real training facilities.
Together with DB, we have virtually mapped part of the company’s infrastructure to bring a training model into the classroom and thus convey content to new employees and career changers digitally, using augmented reality. This way we improve the training quality, the security of action and the interaction between theory and practice. 3D representations of switches are projected into virtual space using augmented reality (AR) glasses. The realistic holograms can be rotated in all directions, functional processes can be triggered and displayed as animations with just a fingertip on virtual buttons. In this way, the assembly of point locks or the elimination of point faults is trained in a technically sound manner without great effort for the employees. Graphically prepared step-by-step instructions enable repairs in real time. The positive effect for rail customers: turnouts are cleared faster and rail operations run more reliably.
The virtual content can be played on AR glasses such as Microsoft Hololens as well as on tablets. 3D Durchblick was rolled out in 8 DB Netz training centers where it runs on the HoloLens. The 8000 technicians can also use the application on their Android tablets outside of training hours. The project was successfully rolled out so that 3D Durchblick is an integral part of the DB Netz AG qualification landscape. Together we continuously integrate new content in the app.
