C.A.S Rail

C.A.S Rail are a skilled team of Signalling Designers with additional expertise in planning and conducting signalling correlation and surveys. 

Location & Relocatable Equipment Building Correlation

Detailed correlation and condition assessments of any trackside enclosures and equipment. We will expertly assess the source records against the current state of the site. We can provide partial and full correlation where required.

Signal Box & Relay Room Correlation

Undertake correlation of signal box infrastructure, such as illuminated diagrams, panels and block shelves. We can also undertake correlation on a variety of interlocking systems.

Bonding Plan Correlation

Provide a complete bonding plan review, ensuring equipment and bonding arrangements are accounted for. We will also confirm the arrangements of the train detection system to the source records, and that the system is free of non-compliances or maintenance alterations.

Signalling Plan / Location Area Plan Correlation

A full review of Signalling Plans and Location Area Plans.

We wheel out sites to ensure the scale of the base source records are correct and reflect the true state of the infrastructure and layout.

We can also provide a full cable route survey, and report on the condition and capacity of the cable route

Correlation & Condition Assessment Reports

Upon completion of the correlation activities, we can provide a Correlation and Condition Assessment Report, produced and verified by licenced Signalling Designers and Verifiers. 

The report will highlight all discrepancies found, with advice on how to rectify issues which will impact the detailed design.

C.A.S Rail can also provide support in:

• Work Package Plans (WPP) and Task Briefs (TBS).
• Cable Route Capacity and Condition Surveys.
• Facilitation of generic Site Surveys, eg, Multi-disciplinary/feasibility walkouts.
• Access Planning to support Correlation and general site activities.
