The offset Sportal concept would provide a projectwith many benefits, including but not limited to:
The portal could be installed without requiring any headspan modifications, therefore a high quantity could be installed during NBS access periods with lower risk to RTHB. Main steel and SPS installation is curtailable in the new option
Less risk posed to conversion with regard existing mast orientation, as top wire removal is no longer a pre requisite to portal installation.
The transferring of the OLE to SIC / MIR style support and registrations could then be staged and tailored to specific areas and access regimes. This could be completed incrementally or wholesale based on access and resource, providing a wide array of benefits & efficiencies and massively mitigating DWWP risks
Having worked on Crossrail West where 4 locations were converted shortly after the ECML trial, the belief was that extensive ALB possessions were a dependency (all 4 were completed over 2 Xmas blockades), but this novel approach adds a whole new perspective to MVP optioneering / SPEED logic assessment for life expired headspan assets, making full conversion and the benefits that brings a more viable option, allowing critical areas such as stations, level crossings and crossovers to be considered
Headspan conversions
Working collaboratively with Keltbray, Wentworth House Rail Systems Ltd have developed a headspan conversion concept design which;
• de-risks construction activities (through independent installation)
• reduces installation costs
• increases installation efficiency
• improves railway system resilience
The SPortal (side mounted portal) enables Main Part Steel (MPS), Small Part Steel (SPS) and
Mechanically Independent Registrations (MIR) to be installed prior to any spanwire modifications.
