Phased strategy
 Finalize existing applications integration mainly
voice oriented
 Include present fixed line applications
 Integrate ETCS application using Circuit
switched Data
 Add new applications to GSM-R using new
GSM features:
 Packet data (GPRS) & Video (EDGE)
 Location systems

Passengers and operational applications in Netherlands
Application
Description
Status
QuoVadis
Measurement systems along the track obtaining
information about passing trains (e.g. weight, speed,
number of axes, wheel quality). Obtained data is sent to a
server via GPRS.
Operational
POSS
Quality monitoring of railway switches (the quality of a
switch is determined by sending a current through it and
monitor the electrical behaviour). Obtained data is locally
gathered and sent to a server via GPRS.
Operational
HSM
Pilot application about information services for drivers.
Drivers get visual information via GPRS on a PDA about
their environment when driving a train (e.g. disturbances,
graphic overview of other trains in the neighbourhood,
connecting trains)
Operational
Webmail ProRail
Mobile access of railway personnel to ProRail web mail
(Outlook Web Access) with a laptop
Implementation finalized in Q2 2006

GSM-R ability to perform
 Open Architecture of GSM-R network
 Leverages upon Public Land Mobile Network
evolution
 In Europe
 worldwide
 Market size significant for PMR equipment and
developing
21
Issues
 Requires end to end solution for applications
including mobile and fixed terminals
 Coordination between Train Operating
Companies & Infrastructure Managers
 Harmonization of software releases
 Ability of evolution of GSM-R hardware &
software to follow public market
 System capacity (limited bandwidth)
 ASCI integration with new features
22
Conclusion: OPERATE
 Technology is available
 New applications can be supported
Maintaining interoperability is a must
 Testing and integration among end to end
all systems (including ERTMS) is an issue
OPERATE: Open Platform Enabling Railway
Applications Testing in Europe is essential
