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.
