Background

Following submission of SSL’s Modular Signalling proposal in April 2008, Network Rail awarded the GRIP 4 contract for the first Modular Signalling pilot scheme (Ely-Thetford-Norwich) in July 2009. Modular Signalling is the new approach to the renewal of signalling equipment on secondary routes under ROGS regime. This new method aims to deliver:

• - Significant reductions in the cost to develop, design, install and test;
• - Significant reductions in scheme development time (GRIP 1-4);
• - Significant reductions in detailed design time (GRIP 5);
• - Significant reductions in Installations/ Test / Commission time.
• - New Tools and Processes to deliver the above reductions.
• - The ‘Modular Signalling handbook’ with Network Rail.

The Modular Signalling Key Features are:

• - The solution is to be aimed for secondary or rural routes
• - Simplified signalling (typically 2-aspect) with uni- and bi-directional schemes
• - Signaller controlling up to 250 Signalling Equivalent Units
• - Maximum use to be made of Network Rails Fixed Telecoms Network (FTN)

Project Scope

The Key deliverables for the Project were as follows:

• - Factory demonstration of fully configured signalling system was completed on time, with acceptance received from Clients Representative. The system shows fully working SI-REB, Smartlock & IECC, Signals and Trackside Equipment. So far the demonstrations have been delivered to over 250 people from a combination of Network Rail, Train and Freight operating companies.
• - Generic Application Safety Cases (System, Product & Process) Produced and submitted to ISPR.
• - Provision of full system architecture document for the solution.
• - Provision of fully detailed product specifications with appropriate standard designs for Signalling, Civil / structural engineering, Telecoms (Inc. FTN integration) and the Power supply sub system and components.
• - Provision of derogations and product approval required for the solution.
• - Power Form EA Design and Telecoms AIP Design.
• - Provision of a report on the design life of the components of SSL's modular solution.
• - Provision of fully developed, verified and validated process and tools for design production, verification and validation, or progress towards completion in accordance with product acceptance plan.
• - Provision of full and effective documentation and tools such that modification of the system by addition, removal or substitution of modules can be undertaken.
• - Screen Layouts for MMI.
• - Production of Track Plans and associated documentation.
• - Provision of Level Crossing Ground Plans and associated Form A and B design, inc. 7 No. MDC-OD Level Crossings.
