This paper contains data for the restoration of axle counter sections from a VDU MMI system via a Solid State Interlocking.

Purpose of Paper

The purpose is to gain approval of the following SSI data solutions. With the exception of Part B, these are for VDU MMI systems. The solutions also contain the necessary panel processor data to allow testing of the interlocking data on a Design Workstation independently of the VDU MMI system.

The document is divided into three sections:-

Part A - Core Restoration Data

Part B - Sequential Proving of Tracks at Interlocking Boundaries

Part C - Pre-Planned Override of Aspect Restriction associated with Axle Counter Restoration
