Core Valley Lines Transformation
Cumming Group provided Cost Management and advisory services for the Core Valley Lines (CVL) Phase 2, part of the South Wales Metro, a £738 million programme designed to enhance connectivity for the 1.5 million people living and working in the Cardiff Capital Region.
The scheme delivers infrastructure improvements to enable faster journey times and increased service frequency on routes between Cardiff and Merthyr Tydfil, Aberdare, Treherbert, Rhymney, and Coryton.
Key works include 25kV Overhead Line Electrification across 172km of track, incorporating permanently earthed sections to minimise disruption to existing structures.
The programme supports the introduction of a new fleet of rolling stock, delivering faster, more frequent, and reliable services, and represents a significant capital investment in the region’s sustainable transport network.
