RSP selected the GRP enclosure manufacturer and all internal equipment manufacturers/suppliers, in agreement with the client, taking into account the availability of items and delivery times.
RSP Installation Team fitted and wired the equipment within the DNOs.
RSP Test Team carried out the Factory Acceptance Tests, verifying that the equipment was built and operating in accordance with the design specifications and all relevant Network Rail & Railway Group Standards.
The DNO cubicles were completed to the agreed timescale and were successfully delivered to site, ready for Commissioning in Spring 2020. RSP takes pride in ensuring that all goods dispatched from our premises are:
