The track removed from the Severn Tunnel during its recent upgrade will be repurposed as sidings at the Global Centre of Rail Excellence (GCRE). Instead of discarding the track from this year’s renewal, Network Rail has successfully recycled all four miles of it. Half of the track has been allocated to the GCRE rail innovation facility in development in Wales, while the remaining half has been processed for use by Network Rail’s maintenance team.
The second shipment of track from the Severn Tunnel has been dispatched to the GCRE facility near Onllwyn. This recent delivery, which arrived over the summer, adds to the two miles of track received by GCRE last year, which are now in use at the site.
