II.2.4) Description of the procurement
TfW intends to award a supply contract to Siemens Mobility for the purchase of Side entry 8DA11 CGIS (Contained Gas Insulated Switchgear). Transport for Wales (TfW), and its delivery partners, are responsible for the development and delivery of the South Wales Metro, including the CVL Transformation programme, which will integrate public transport services and systems in South East Wales. Part of this programme includes the electrification of the Core Valley Lines in South East Wales (comprising Rhymey to Cardiff Queen Street, Coryton Spur, Merthyr Tydfil to Cardiff Queen Street, Aberdare to Cardiff Queen Street, Aberdare to Hirwaun, Treherbert to Cardiff Queen Street, Cardiff Queen Street to Cardiff Central and Cardiff Central to Cardiff Bay) and will require supply and fixing of substations to create the power network.
TfW has identified that Siemens Mobility is the only supplier capable of meeting TfW’s requirements, for the following reasons. The required items must be supplied by a Network Rail Parts and Drawings System ("PADS") approved supplier of side entry 8DA11 CGIS (Contained Gas Insulated Switchgear) in order to conform to Network Rail and TfW standards, namely NR/L1/ELP/27000, NR standard NR/PS/ELP/27236 and PADS Certificate PA05/00637, including as well the following British Standards policies and legislations as detailed in NR/L1/ELP/27000:
BS7671 – Requirements for electrical installations
BS EN 50119 – Railway applications. Fixed installations. Electric traction overhead contact lines.
BS EN 50122 - Railway applications. Fixed installations. Electrical safety, earthing and the return circuit
BS EN 50149 - Railway applications. Fixed installations. Electric traction. Copper and copper alloy grooved contact wires
BS EN 50163 & A1 – Railway Applications. Supply voltages of traction systems
BS EN 50367 – Railway applications. Current collection systems. Technical criteria for the interaction between opantograph and overhead line (to achieve free access)
BS EN 50388 – Railway Applications. Power supply and rolling stock. Technical criteria for the coordination between power supply (substation) and rolling stock
BS EN 50463-4 – Railway Applications. Energy measurement on board trains. Communication

The supplier must be PADS approved because the product acceptance process gives TfW the assurance that products accepted for use on or about the infrastructure are safe, compatible, reliable, fit for purpose and do not export unacceptable risks to Network Rail and/or TfW infrastructure. The supplier must also have side entry cable capacity to ensure conformity with the standards detailed above and to meet the system design requirements where due consideration was given to all types of design and decisions based on concerns regarding land take and consents and potential for vandalism have led to the requirement for CGIS Switchgear. TfW's expert advisers have conducted market investigations and on the basis of these it appears that Siemens is currently the only PADS approved supplier of CGIS switchgear with side entry which meets the above requirements.
