The Train Control System solution
Facilitates transport operations
HOW DOES IT WORK?
Interacts with the interlocking (IXL) and the Automatic Train Control
(ATC) to monitor and control the transport system operations.
Simultaneously orchestrates traffic management and
operational functions through a modular design fit for integration:
– ATS for Automated Train Supervision
– CTC for Centralized Traffic Control
– SCADA for infrastructure monitoring
– Security for video surveillance and communications

Processing
The data acquisition and field interface provides the capability to acquire data from various sources using specialized equipment such
as front-end-processors (FEP), remote terminal units (RTU), programmable logic controllers (PLC), remote I/Os (RIO), field buses etc.
The communication backbone is usually procured by the Transport customers separately from the control center.
The supervisory control package fulfills the standard functions of a SCADA with its human-machine-interface (HMI).
The automation level performs automatic controls of the trains and field devices based on pre-defined planning, data triggers and/or
result of complex algorithms. Automatic Route Setting and Automatic Traffic Regulation are typical traffic management functions.
Automatic ventilation strategies and control sequences are typical station and infrastructure management functions.
The optimization level performs an analysis of the overall transport system performance dependent of many constraints and parameter,
deterministic or not. Non-linear programming, heuristics and stochastic methods can be applied to obtain a good or optimal solution.
Service oriented architectures allow for publishing data and services between the components of the control center and with third party
supervision systems. The service interface exposes and utilizes services between systems.
Many control center tools are required to perform data configuration, simulation, generate timetables, perform maintenance etc.

Safety
Strategy based on user needs analysis
• The ATS/CTC software shall be developed according to the EN50128-2011
CENELEC standard
• The following functions of ATS/CTC can be considered safety-related:
- The verification and generation of route controls
- The ATS/CTC shall not challenge the signaling system by requesting
unsafe route
- The request and display of Train Speed Restrictions, Possessions, Train
Hold/Skip
Trends from European market
Trafikverket NTL – Sweden
Customer challenges
• Reduce the number of regional CTCs from 8 to 4,
• Ensure the CTCs are ERTMS L2 ready as ERTMS roll-out will be done in
parallel,
• Control any part of the country from any CTCs: dynamic reallocation of
control rights, optimization of traffic.
• Standardisation & enhancement of ways of working and operating procedure.
TMS UK
Customer challenges
• Moving from 870 signal boxes to 14 operating centers
• Implement Regional TMS: short-term optimisation, perturbation mgt, conflict
detection and solution, …
• Implement National TMS: long-term optimization, infrastructure
availability,…
• Maintain and enhance external interfaces: passenger, TOC, FOC…
• Old infrastructures with complex topology not always designed to support high
density traffic.
Trend from European market
Recuring features
Large areas (National or Regional) management implies three recurring features
• Needs of coordination between all actors involved
in the traffic (TOCs, Maintainers, …):
ICONIS Task Management
• Needs of effective optimization algorithms
