Computer Aided Testing Systems (CATS)
Country: United Kingdom
The CATS system has been developed specifically to meet the varied requirements of the signalling testing and commissioning process. Currently, during the renewals process the testing of interlockings can be difficult due to a scarcity of qualified testing resource and a lack of tools to assist the testers during testing. The process is also usually subject to tight timescales within possessions.

Key Features and Benefits

  • The CATS system interfaces seamlessly with any type of relay based interlocking and communicates with the user via a robust and easy to use Windows based word package. This therefore provides the signalling tester with a valuable tool which assists them in all stages in the testing process.
  • All actions taken by the tester are recorded and written to disk for later auditing/analysis. This allows faults to be located more quickly and easily during the testing process and provides proof of interlocking at handback.
  • CATS provides a cost effective solution giving the following benefits

    Increased safety
    Increased labour efficiency
    Reduced risk of over-runs
    Improved records of testing for audit purposes

Importantly, the CATS service provides supplementary technical and signalling expertise for the Renewals contractor.

Suitable Applications

CATS can assist with the testing of the following:

  • Geographical interlockings
  • Free wired interlockings
  • Level crossings
  • Other legacy signalling systems

We provide the following testing services:

  • Geographical set testing
  • Line side signalling equipment simulation
  • Signaller's panel simulation
  • Level crossing simulation (CCTV, AHDB, MCB)
  • Design simulation
  • TDM simulation
  • Lever frame simulation
