Presentation Topics• New Developments in the Interoperability of Train Control Systems– Background to 4Tel Pty Ltd–Why is harmonisation stifling innovation?–Why can interoperability promote innovation?–Where should each be used for best purpose?– How these issues are solved on the NSW Country Regional Network

18 August, 2015 4Tel Pty Ltd Page -‐ 2


Background• 4Tel designed, built, commissioned and now maintains the network control & technology services for John Holland Rail for the NSW Country Rail Network under contract until 2021

• Will share our experience in developing interoperable technology for rail use, including safety applications



John Holland Rail• JHR won tender to deliver rail network operations and

all maintenance services for the NSW CRN from 16Jan12• Expected revenue of $AUD 1.5 Billion over 10 years• Manages 5,800 km of track across regional NSW for the

NSW Government– 2,400 km of operational lines and 3,400 km of non-‐operational

lines.– More than 400 employees – Additional 27,000 hectares of land is under management, – 600 rail under-‐bridges and 384 road bridges

INTEROPERABILITY

Interoperability is achieved by defining the interface standards for systems to connect to each other; not by harmonising all purchases



What is the Goal of Interoperability?• A core outcome is that the competitive tension of ideas must prevail while preserving safety:– Any third party must be able to connect– Any third party must be able to innovate– Any supply-‐chain monopoly structures must be changed to a competitive basis

• How should open-‐systems work:– The key is reliable, timely data managed by safety-‐accredited processes



The Goal is Safety at the Application Layer


• Digital systems work differently

• Safety is an app issue; not media or host!!

• Interfaces between Layers in a system

• Protocols between same Layers

• The Internet uses Open Systems standards

Interoperability is achieved via network connection & interfaces


Is Harmonisation Interoperability?• Harmonisation

– The preferred railway systems approach as all systems are the same

– And ‘One Approved Way’ lowers risks

• BUT – Creates monopoly rents and higher prices– Stifles new features and innovation– Creates uncompetitive barriers-‐to-‐entry– Limits system integration or separation– Requires universal use of the same operating rules for safe operations



Interoperability is Different• Interoperability– Is demanding on interface standards & certification

• BUT–Allows separation of complex systems–Allows integration of new systems– Promotes innovation by allowing competitive features and functions



Interoperability Versus Harmonisation• Users should be able

to buy on the basis of what features and functions they need

• Then seek the security credentials they need to operate

• At no time should a user need to worry about “How do we connect?”



An Interoperable Train Control System• Users connect by

obtaining connection credentials, e.g. a SIM

• Users then seek the data encryption keys and the security credentials they need to operate

• Users then download the features and functions they need

The biggest security riskis an authorised person doing an unauthorised action, not hacking, in aprofessionally designedsystem. This has always been so.


Interoperability in Open Systems• Three core elements are needed to achieve interoperability between systems:– Methodology for network connections – IP DATA

– Methodology for describing data -‐ XML– Methodology for achieving security and operational integrity – ENCRYPTION & CREDENTIALS MANAGEMENT

• Interoperability is NOT Harmonisation

Standardise Interfaces, not the Systems


Proprietary systems allow innovation to improve services & value-‐for-‐money

Harmonised systems can stifle innovation & create monopoly rents



CRN Secured & Defined Interfaces



Interoperable Data on the CRN


NSW COUNTRY REGIONAL NETWORK INTEROPERABLE TECHNOLOGY

Interoperable technology greatly improves situational awareness and removes all dark territory




RSML Interfaces are under formal Configuration Control

4Tel uses a “Rail Systems Markup Language” (RSML)℗for data interoperability betweenproprietary computer systems℗ Innovation Patent Aust: #2015100253

Rail Systems Mark-‐up Language


TRAIN CONTROL

To reduce risks and deployment costs, operate with voice working with SIL-‐2 tracking, using existing radios in locos



Digital Train Control



Modern Radio-‐Based Interlocking• Similar train throughput to CTC but minor field

infrastructure• Optimised for any single track line with crossing loops• SIL-‐2 certified to IEC 61508 • Voice and Electronic Operations• Electronic interface to Open Access Billing & Train

Planning Systems• Electronic graphs & reports• Very high availability



Harmonised Radio Modes• Radio spectrum and modes needs to be defined to provide flexibility to industry

• A harmonised suite of radios types is used:– 2G/3G/4G Mobile for economical coverage– Satellite Mobile, for ubiquitous geographical coverage – UHF 400 MHz Band for Private Mobile Radio (PMR)

• FM, 12.5 kHz; DMR, 6.25 kHz

– GSM-‐R at 1,800 MHz for ETCS L2 compatibility– Satellite navigation tracking

• One shared User Interface HMI18 August, 2015 4Tel Pty Ltd Page -‐ 24


In-‐Cabin Equipment (ICE) Train Radio



Locomotive Installation• An ICE Human Machine Interface (HMI) is provided for Driver use

• Mounted on a pedestal or in a panel



TMACS Voice & Electronic Authorities

• Safety accredited to SIL-2 under IEC 61508

• Used for simultaneous mixed fleet working
