5. Recalling the discussion at the previous GRSG session on ECE/TRANS/WP.29/GRSG/2016/20, the expert from Switzerland presented GRSG-112-02-Rev.1 proposing to simplify the provisions of UN Regulation No. 107 by inserting references to parts 1 and 2 of the forthcoming updated European standards EN 16584:2015 on railway applications for persons with reduced mobility (GRSG-112-03 and GRSG-112-04). The expert from France preferred to leave these requirements out of the Regulation to avoid possible inconsistencies with existing national requirements. A number of experts preferred to keep some of the requirements proposed in GRSG-111-35 within the Regulation, but to improve the wording of the provisions concerned. Following the discussion, GRSG adopted ECE/TRANS/WP.29/GRSG/2016/20 as amended by GRSG-112-35 and agreed to submit it to WP.29 as a new 08 series of amendments to UN Regulation No. 107. Thus, the expert from OICA volunteered to prepare, in due time, a revised official document for consideration and final adoption at the next GRSG session, including the proposed transitional provisions (i.e. June 2020 for new types of vehicles and June 2022 for all existing types).
