Northern Trains Ltd is publishing this notice to establish a contract to design and construct OHLE isolations that is present on roads 1-3 in the maintenance shed at Allerton Train Care Centre. The Scope of requirements for design shall be to develop the designs to AFC status standard in accordance with the relevant Network Rail Standards and to provide a submission to NWR for Engineering Assurance. The Scope of requirements for Construction shall be to implement the designs across the OHLE that is present on roads 1-3 in the maintenance shed at Allerton. This project seeks to provide the ability for the TCC to isolate the OHLE quickly and safely within the maintenance shed when high level access is required on the units within the shed. The existing isolators are manually operated MLE 1250A designs with earth position to the current design. The manual operating gear will be removed and be replaced with motor units. New support steelwork will be required to support the motors. The operating tubes from the motor units to the switch / outpost bearings will be replaced with types with universal joints, as the position of the drive on the motor unit is different from that for the manual operating gear. Each isolator moving contact will be fitted with a limit switch assembly, which will be connected to the motor units. The OLE contractor will run the cables from the switches to the motor units but not terminate them. On completion of the installation of the motor unit and limit switch assembly a functional test will be performed to check correct operation. The Depot Protection System [DPS] contractor will need to be attend the test. Additional traction bonds may be required from the earth posts of the isolators to traction return, i.e. duplicate traction bonds. Form A/B, AFC and As Fitted designs will be required for the OLE modifications. A site survey will be required. An IDC will be required with the DPS designer / contractor. Amendments will be required to the Network Rail isolation diagram and possibly the isolation instructions. The depot local isolation instructions will require revision.
