Reasons for Technology Migration
10
It’s all about the money
Getting more performance and safety for less investment
Reducing the cost of infrastructure renewals
Decreased maintenance costs
Optimising the cost of mid-life enhancements
Increased automation – lowering operational costs
Improved safety
Railway Control Systems Developments
Symposium 14th January
In-Cab Signalling Trends
11
›CBTC ›Adopted by metros around the world for both greenfield and brownfield upgrades
›No equipment standardisation between suppliers
›Clients are tied into the supplier for the lifetime of the system
›ETCS ›Standardisation imposed to achieve interoperability
›Mandated by law for mainline railway upgrades in the EU, but adopted elsewhere too
›Standardisation limited to constituent sub-system interfaces
›Requires country specific operational design
›PTC ›Communication based ATP system mandated by American law for freight and passenger
›Deadline for implementation extended to end of 2018 (3 year extension)
Railway Control Systems Developments
Symposium 14th January
In-Cab Signalling Convergence
12
›CBTC, ETCS and PTC all have the same objectives:
›Continuous speed supervision – protection against derailments from excessive speed
›Protection against train to train and train to buffer stop collision
›Prevention of train movements through points in the wrong lie
›Protection of maintenance possessions from unauthorised train movements
So why can’t one solution meet all these requirements?

Symposium 14th January
Signalling Control Trends
13
›It’s all about the money!
›Centralisation
›Train regulation
›Improved recovery from disturbances
›Quicker response and control in degraded modes
›Improved management emergency situations
›Possibility of backup control facilities and transfer of control
›Operational/passenger control – not just signalling control
