About this event

ICE Wales Cymru Ground Engineering Group (GEG) have organised this event.

Speaker: Dr Kevin Briggs

Trees cover the slopes of many earthworks (embankments and cuttings) supporting the UK's rail network in both urban and rural areas. They provide a habitat for animals and plants, while providing a visual and acoustic screen for local residents.

However, some trees can cause seasonal shrinking and swelling of the railway track, leading to a substantial maintenance cost for infrastructure owners. Guidance is required to identify and manage the removal of problematic trees, while avoiding full tree clearance on earthwork slopes.

Two case studies are presented which identify 'problematic' tree species and demonstrate the positive and negative impacts of tree removal on railway earthwork slopes.

This is a free event and light refreshments will be served at 5.30 before the lecture which will start at 6.00pm.
