At its 74th session, GRE discussed proposals concerning electromagnetic compatibility and trolleybuses. Given the diversity of views, including from Belgium, China, Finland, and Russia, GRE decided to establish this task force in order to ensure that the views of national authorities and other stakeholders in this issue would be fully taken into account before proceeding with a concrete proposal. OICA volunteered to act as the task force secretary. The original base documents for the group discussion include GRE-74-12 (Russia) and GRE/2015/36 (China).
