Technician’s Terminal


MT04S - Technician's Terminal

The components and hardware used in the Solid-State Interlocking (SSI) Technician’s Terminal, manufactured by Alstom and Westinghouse, are now obsolete.

Park Signalling has developed a replacement Technician’s Terminal (type reference MT04S) using standard Commercial Off-The-Shelf (COTS) components.

The technologies used have been carefully chosen with consideration for longevity.

A major consideration in the development was to provide a replacement for the original Technician’s Terminal which is directly compatible at the electrical interfaces. Park Signalling have developed a modern, graphical user interface which is more intuitive, easier to use and displays information more clearly.

This is Network Rail product approved.
