TDM completed CIS installation across twenty railway stations for Great Western Railway, with Parson Street receiving a complete CIS and PA system. As part of this project, we designed and manufactured all mounting brackets and columns in-house, ensuring each solution was tailored to its specific environment. The work spanned a wide range of locations, from major hubs like Oxford and Exeter St David’s to smaller rural stations – including three listed buildings that required heritage-compliant solutions.
To ensure consistent delivery across all twenty sites, TDM developed a comprehensive project management framework from the outset. In addition, we conducted detailed surveys at every location to assess individual requirements before any work began.
As a result of this preparation, we were able to:
This GWR project demonstrated TDM’s ability to manage complex, geographically dispersed CIS installation across railway stations of varying size and heritage status, whilst maintaining consistent quality throughout. Furthermore, the successful coordination of twenty simultaneous installations showcased our robust project management capabilities and technical expertise.
Consequently, this project established TDM as a reliable partner for large-scale network improvements – capable of delivering standardised solutions whilst respecting individual site constraints and heritage requirements.
