Tomorrow's Railway and Climate Change Adaptation Final Report

Of all the CCS assets, location cabinets have been identified as being at most risk of
overheating, particularly older assets. It is recognised that in the longer term, European
Rail Traffic Management System (ERTMS) level 3 radio-based signalling will remove the
need for much lineside equipment. It is recommended that the industry identify and
prioritise older location cabinets so they can be monitored in the period before an
upgrade takes place.
Network Rail has done extensive work to quantify the thresholds above which increased
asset failures occur. It has not yet reported on what the performance and cost impacts
above these identified thresholds are, but it is anticipated that this will be useful and
valuable information.
Stakeholder workshops identified that there was insufficient knowledge about the effect
of switches and crossings on the stress free temperature of rails. Further research is
needed into this area.
