5. Recalling the discussion on ECE/TRANS/WP.29/GRSG/2015/21 at the previous GRSG session, the expert from Romania introduced GRSG-110-03 clarifying the requirements on seat spacing and superseding the official document. The expert from OICA introduced GRSG-110-09 amending the provisions on the use of the gaging devices in the case of monitor or display devices mounted at the ceiling of buses and coaches. The expert from Italy presented GRSG-110-21 to align the 05, 06 and 07 series of amendments of UN Regulation No. 107 with the requirements of Supplement 4 to the 04 series of amendments concerning barriers in the gangway and the amount of priority seats in buses and coaches. GRSG adopted the proposals as reproduced in Annex II to the report and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their November 2016 sessions, as draft Supplements to the 04, 05, 06 and 07 series of amendments to UN Regulation No. 107.
6. The expert from Belgium presented ECE/TRANS/WP.29/GRSG/2016/5 proposing to remove the new safety prescriptions for trolleybuses from UN Regulation No. 107 and insert them into UN Regulation No. 100 on electric power trained vehicles. The expert from UK raised concerns about the differences in the scopes of both Regulations and their application to trolleybuses. GRSG noted the comments by the Working Party on Lighting and Light-Signalling (GRE) about possible alignments of UN Regulations Nos. 107 and 116 with UN Regulation No. 10 on electromagnetic-compatibility (GRSG-110-04). The expert from OICA introduced GRSG-110-08-Rev.1 on the applicability of UN Regulation No. 100 versus Annex 12 of UN Regulation No. 107 with respect to electrical safety provisions. The expert from France explained that the origin of the current problem of trolleybuses was linked to the application of the European Union (EU) legislation on whole vehicle type approval. The expert from Japan informed GRSG about the intention of the Chair of GRE to seek the advice of WP.29 on this subject at the forthcoming session in June 2016. The GRSG Chair questioned the need to also involve the experts of the Working Party on Passive Safety (GRSP) in charge of UN Regulation No. 100. A number of experts expressed their preference to keep the electric safety provisions within UN Regulation No. 107. Thus, GRSG agreed that the experts of the Working Parties concerned should work on a simple solution avoiding further burden for public transport operators. The expert from Belgium volunteered to conduct a more detailed analysis on the compatibility or incompatibility of the scopes and technical provisions for trolleybuses of UN Regulations Nos. 10, 100 and 107.
7. GRSG agreed to resume consideration of this subject at its next session in October 2016 awaiting the outcome of the analysis by Belgium. GRSG requested the secretariat to keep ECE/TRANS/WP.29/GRSG/2016/5 on the agenda as a reference document.
