Evaluation of train remote control via tablet in a railway model layout

Abstract

Evaluation of train remote control via tablet in a model railway layout In the project ARTE (Automated Regional Trains in Lower Saxony), we investigate driverless operation in grade of automation (GoA) 3/4 on regional lines. An important component is the development and investigation of remote train operation (RTO) as a fallback solution in the event of automatic train operation (ATO) failure or other incidents. One aim is to implement a simplified remote control system that can be operated by either train personnel or a remote train operator. A user test with 13 participants was carried out in a model railway layout in order to check whether remote control using a tablet and the Z21 model railway app is practicable. After an introduction to the tablet and the app, participants remotely drove a model train in timetable mode. After that, participants completed the SUS and a questionnaire regarding tablet control with the app. Overall, the user test showed that remote control is feasible using a tablet and the Z21 app. The key findings were that route knowledge is also required for remote control and that the video image must be of sufficient size and quality. Further optimisation requirements for using this tablet solution for the remote control of a real train were identified.
