Join RSSB's team for updates to the September standards catalogue including revisions to the guidance around using GSM-R, walking on or near the line, and drivers’ use of audible warnings. They also cover operating route- and line-proving trains and introduce new signs for certain types of permissible and temporary speed restrictions, as well as their application. Presentations will also cover rolling stock compatibility with CCS subsystems and the outputs from the research project into the review of the risks associated with using hydrogen-fuelled rolling stock.
