Permanent Way (PERWAY) Design & Engineering

Including Drainage and Signalling Integration

We provide PERWAY design services developed in alignment with new and upgraded signalling routes, ensuring full integration between track layout, turnouts, earthworks, drainage systems, and signalling interfaces.

Our PERWAY design services include:

  • Review of existing track layouts, as-built records, and condition assessments
  • Track geometry, alignment, gradient, and clearance optimisation
  • Turnout and special trackwork layout design
  • Formation, ballast, and subgrade design inputs
  • Drainage design for surface and sub-surface water management, including catchwater drains, longitudinal drains, cross drains, and outlet structures
  • Mitigation of water ingress risks affecting track circuits, axle counters, and formation stability
  • Coordination of signalling, telecoms, and electrical interfaces
  • Constructability reviews aligned to mechanised installation methods

 

Construction and Maintenance of PERWAY Works

With Integrated Earthworks and Drainage

We deliver integrated PERWAY construction services using mechanised methods to ensure precision, consistency, and durability.

Our scope includes:

  • Earthworks and formation rehabilitation, including removal of fouled materials
  • Construction and rehabilitation of surface and sub-surface drainage systems to control water flow and prevent formation saturation
  • Installation of ballast layers, sleepers, rails, and fastening systems
  • Construction and renewal of turnouts and special trackwork
  • Certified rail welding (alumino-thermic) and joint finishing
  • Mechanised tamping, ballast regulation, and geometry correction
  • Final inspection, testing, and handover documentation
  • Track condition assessment to determine asset condition

All works are executed in accordance with approved designs, railway standards and safety requirements.

Turnout Replacement Using On-Track Machinery

Including Track Material Supply, Earthworks, Drainage and Welding

We undertake complete turnout replacement projects within live rail corridors and planned shutdowns, recognising that effective drainage is critical to turnout performance.

Our turnout replacement services include:

  • Removal and installation of turnouts and track panels
  • Bulk earthworks and formation rehabilitation within turnout zones
  • Supply of complete track material within the turnout scope
  • Construction and rehabilitation of localised drainage systems to prevent water accumulation beneath turnouts
  • Precision alignment of switch rails, closure rails, and crossings
  • Certified rail welding, grinding, and inspection
  • Mechanised tamping and ballast regulation

Testing, commissioning, and certification

Earthworks, Formation & Drainage Engineering

We address the root causes of track degradation through comprehensive earthworks and drainage engineering.

Our services include:

  • Extensive asset condition testing to determine the scope
  • Excavation and removal of failed or fouled formation materials
  • Formation and subgrade rehabilitation to specified standards
  • Construction and rehabilitation of surface drainage, including side drains, mitre drains, and catchwater drains
  • Installation of sub-surface drainage, including filter drains and cross-track drainage
  • Embankment stabilisation and erosion control
  • Compaction and in-situ quality control testing
  • drainage flow
  • Geometry correction and verification

Ballast Tamping Using On-Track Tamping Machinery

Ballast tamping is the core mechanised maintenance activity undertaken to correct track settlement and geometry defects.

  • Lifting of track to the required design level
  • Lining of track to correct horizontal alignment
  • Levelling to achieve correct vertical geometry and cross-level
  • Compaction of ballast beneath sleepers to restore bearing capacity
  • Correction of geometry defects, including:
    • Gauge deviation
    • Twist and cross-level defects
    • Vertical and horizontal misalignment

Ballast Regulation and Profiling

Ballast regulation is undertaken as an essential complementary activity to tamping and general maintenance.

  • Redistribution of ballast within the crib area
  • Shaping and compaction of ballast shoulders to provide lateral track restraint
  • Removal of excess ballast from rail seats, sleepers, and fastenings
  • Formation of correct ballast profiles to facilitate effective drainage

Rail Welding Services

We deliver certified rail welding as part of construction and renewal works, ensuring structural continuity and consistent track performance through:

  • Alumino-thermic welding of rails and turnout connections
  • Grinding and profiling of welded joints
  • Visual and non-destructive testing where specified
  • Welding certification and documentation

Electrified Corridor & OHTE Interface Works

We operate safely within electrified rail corridors, coordinating rail, drainage, and earthworks activities with overhead line equipment systems through:

  • Deployment of certified on-track overhead platforms
  • Electrical isolation and permit-to-work systems
  • Rail–OHTE interface works
  • Coordination with electrical and signalling teams

Safety, Quality & Compliance

All services are delivered under robust governance frameworks, including:

  • Rail Safety Regulator (RSR) compliance
  • Approved method statements and risk assessments
  • Inspection and Test Plans (ITPs)
  • Certified operators, welders, and supervisors
  • Continuous safety, quality, and environmental monitoring
