Immersive technology

Augmented education is bringing trains and switches to the classroom

Immersion puts users into a virtual world that feels entirely real. Immersive technologies, like virtual reality (VR) and augmented reality (AR), either create a reality that is entirely virtual (VR) or use certain virtual information to map out reality (AR). These technologies usually rely on special glasses that allow reality to be blended with a virtual world. Smart phones can be used as well.

Virtual and augmented reality have been an integral part of vocational training and professional development at Deutsche Bahn since 2018. In this digital age, professions in the rail industry increasingly require specialized expertise. Railroad installations and facilities are constantly evolving and people need to learn how to use new technologies quickly. DB uses its own virtual reality application called Engaging Virtual Education (EVE) to train its employees. VISCOPIC, a Munich startup in the DB mindbox incubator program, has also developed virtual training using realistic holograms of switches.

Virtual training on an ICE4 with EVE

Train crews need regular training not only on how to operate new trains; they also need to know the ins and outs of existing classes of trains. EVE and VR glasses give train crews a virtual learning environment that records natural movements and actions. EVE makes training hands-on, which reinforces learning.

This VR training has been part of regular training for on-board service crews since 2018. Crews learn how to operate the wheelchair lifts installed on ICE4 trains to help safely lift wheelchair users onto the train. One particular sequence involves 28 separate steps. Training exclusively on real trains would be too expensive and time-consuming. The VR training on wheelchair lifts has been offered nationwide at the long distance transport training centers of all nine service management locations since April 2018.

Over 1,000 train crew members had taken the training by the end of 2018, and all 4,000 crew members will have completed the training by 2020.

VISCOPIC uses holograms to train maintenance technicians on switches

DB employs over 8,000 infrastructure maintenance technicians. Half of them will retired by 2026, which means that many new employees will need to be trained. There's no way to bring actual technology, such as switches, into the classroom.

That's why the entrepreneurs at VISCOPIC developed a solution to make rail technology accessible.

The startup uses augmented reality glasses to project three-dimensional illustrations of "heavyweights" like switch drives into the virtual space. The realistic holograms can be turned in every direction, and virtual buttons can be touched to trigger functions, which are then shown as animations. This lets technicians practice how to assemble switch locks and troubleshoot problems with switches.

VISCOPIC's augmented reality solution closes the gap between theory and practice in vocational training and professional development. The "hands-on" solution is better able to illustrate how steps and components fit together so that technicians can confidently translate what they learn to the field. Giving employees optimal training leads to fast corrective and preventative infrastructure maintenance, which in turn means on-time trains. The "3D Durchblick" AR training solution has been offered at DB Netz training centers throughout Germany since May 2018. Over 200 signal and switch mechanics had taken the training by the end of 2018.

Servicing coffee machines step by step with HoloAssist

DB Systel has developed an augmented reality solution that helps employees repair equipment by providing just the information they need. HoloAssist guides technicians step by step through even complex repairs directly on the equipment itself. This is made possible by augmented reality glasses, such as Microsoft HoloLens, which project 3D animations onto the object being repaired to show the next step in the process along with helpful text and audio instructions. To the technician, the actual environment and animated holograms demonstrating repairs appear as one augmented reality. DB employees receive effective training, which helps them put what they learn into practice. Troubleshooting coffee makers on long distance trains is one of the first applications where the solution will soon be used.


Virtual picking and packing training

Experts from DB Schenker and the Fraunhofer Institute have developed an innovative employee training program for packaging and order picking processes at the Enterprise Lab for logistics and digitalization. The training program is built around six exercises that teach the participants about the steps from start to finish in a fun way. In the VR version, employees don 3D glasses to step into a virtual world where they can interact with their workstation and even learn movement sequences. Training in a virtual environment makes it possible to thoroughly test new logistics processes before they are introduced. DB Schenker has used the program in Leipzig since 2018. There are plans to expand the program to other contract logistics sites.
