Clarification of the future

onboard architecture (examples)

• FRMCS(Future Rail Mobile Communication System)

• TIMS, safe length and

train-end-device(Train integrity monitoring systems)

• Updateability,

maintainability,

substitutability and

exchangeability!

ATO

• Highly automated (re)scheduling & control

• High integration of planning functions,

planning, disposition and control in one system

• Precise realtime control („meters and seconds“)

• Risc calculation on runtime, high „changeability“

• Safe for every operational process or asset-layout

• Interlocking and RBC in one system

• Smallest possible amount of SIL4 functions

• Fast and cheap migration in large steps

• Can control every mix of L2/HL3/L3/“L3++“

• Open modular architecture for future extensions

• Ready for larger datacenters

• Open interface

• Independent

lifecycle

• „Plug & Rail“

• Powerfull

degraded modes

• Safety for every subject

& object.

• Efficient train detection

especially for L3

• Field force management-

automation

• Higher Capacity

• Lower energy

consumption

This architecture

allows on the long run

the reduction of the

amount of trackside

assets down to 30%.
