1 network resignalling
1. Network Resignalling

  • Period: 2011-2017 in all PRASA regions

  • Includes:

    • Prasa Regional CTCs

    • Bidirectional traffic

    • Replacing the old technology

  • It is the foundation for Wireless Signalling and correlated with the introduction of the new Rolling Stock

  • Deliverables: Resignalling of all three regions (electronic interlockings, axle counters, led signals, system monitoring,)


Assets protection program today 2014
Assets Protection Program(today – 2014)

  • Lobby for change of legislation for scrap dealers (one regional dealer for Eskom/Prasa/Gautrain, heavy punishment for asset thieves)

  • Protect rail land (brick & electric fence, alarms, video)

  • Code and chip the outside assets starting with copper cables (dot tint, invisible paint)


Optical fibre network
Optical Fibre Network

  • Installation period 2012-2014

  • Will complete the ring for high reliability communication required in Signalling.

  • Became the main mean of communication in signalling eliminating the copper cable.

  • Deliverables: FO rings in each region


Radio digital signalling network
Radio Digital Signalling Network

  • Installation period: 2012-2017

  • Replaces the obsolete analogue trunk radio being back-up for communication and later becoming main communication mean for Signalling.

  • Improve communication to the driver and support data transmission from and to new and oldRolling Stock.

  • Deliverables: Modern signalling networks in all three regions


Wireless signalling mtcs
Wireless Signalling (MTCS)

  • Installation period: 2012 – 2020 (include in the RS tender document the signalling requirements)

  • Increase safety (ATP) and capacity.

  • Eliminates line-side signalling equipment (when complete fleet replaced)


Semi automatic train operation
Semi-Automatic Train Operation

  • Installation period: 2014-2022

  • Automates traffic.

  • Increase frequency of trains


Virtual block
Virtual block

  • Installation period 2016-2025

  • Distance between trains decreases or increases according with traffic requirements.

  • Traffic capacity increased up to maximum line potential.
