2024 – March – Robinson – Barriers to innovation in signalling design, verification, and validation
By: Neil Robinson
Date Presented: March 12th, 2024

I started in signalling more than 30 years ago at British Rail, where I learnt how to design interlockings, initially in relay circuits, and then by programming Solid State Interlockings. This work sparked my interest in safety critical syste

2024 – August – Burns – Human Factors at Level Crossings
By: Peter Burns
Date Presented: August 21st, 2024

Today’s railway fatalities are arguably more likely to occur at level crossings than in the train collisions we tend to focus most attention on controlling. Designing for level crossing safety can be messy and grey, especially when the dependen

2017 – July – Baker – Queensland Rail: AWS to ETCS

Author(s):
Date presented: July 18th, 2017

Brett Baker BE, MBA, MIRSE, MRTSA Queensland Rail The principle form of train protection for the metropolitan rail region of Queensland has been the Automatic Warning system. In 1988 the ERICAB 700 Automatic Train Control system was introduced onto the regional North Coast Line of the Queensland Rail network. It was followed in 1994 by the WESTECT Automatic Train Protection system, which now provides train protection for over 2500 route kilometres on the regional rail network within Queensland. The Automatic Warning System remains the train protection system stalwart for the metropolitan rail network, ERICAB is no longer in use and the WESTECT Automatic Train Protection system is all but life-expired, so Queensland Rail now looks beyond these systems for the future application of train protection for the rail network – European Train Control System.

2017 – March – Moore – Signalling system safety is NOT an absolute

Author(s):
Date presented: March 3rd, 2017

Trevor Moore Hon FIRSE FIEA Aust Australian Rail Track Corporation We often design a signalling system and continue its operation even though there are significant changes in train operating conditions. Do we assume that is still as safe as the day it was commissioned into service? Some cases are self-evident that safety has changed. If we increase the train speed over a level crossing we know that the approach warnings have to be reviewed and updated. Do we check and update if they have changed the road traffic classification to B double trucks? When and how should we review the signalling system for safety of operations? What should be the catalyst to undertaking a review? Should this be part of the standard practice for signal engineers managing infrastructure and for signal designers on new works? The paper addresses some of the situations that can arise leading to a change in the safety of the signalling system.

2017 – March – McDonald – Is RAMS all BULL for Electromechanical Equipment?

Author(s):
Date presented: February 25th, 2017

Wayne McDonald BE (Elec) FIRSE Siemens Limited Railways are required to operate safely and one of the methods to demonstrate this is type approval of signalling equipment. That approval must include documentation of high RAMS (Reliability, Availability, Maintainability and Safety) when applied in vital and even non-vital applications. Suppliers have provided such values, in some form or another, for electrical, electronic and programmable electronic equipment for many years. The limitations and applicability of these values have not always been well understood and they have often been misapplied. The decisions for product comparison or maintenance plans could therefore be compromised or invalid. More recently, purchasers, and personnel assessing type approval are demanding values such as SIL (Safety Integrity Level) and MTBF (Mean Time Between Failure) for electromechanical equipment and systems. The standards currently used for programmable electronic systems clearly state that using them to derive values for electromechanical is inappropriate. This paper delves into the importance of understanding and applying meaningful RAMS values for signalling equipment and addresses the inappropriateness of SIL and MTBF for Electromechanical Equipment. It continues to offer some suggestions for how RAMS can be used for Electromechanical Equipment.

2017 – March – Boshier – Technology based asset management

Author(s):
Date presented: February 25th, 2017

Steve Boshier FIRSE, FCILTA Auckland Transport Asset Management is an area that continues to develop through innovation, technical developments and through new ways of looking at whole of life management. In tough economic times, businesses often take short cuts with asset management in a bid to remain profitable. Its usually one of the first areas whose budget gets cut back for a whole range of reasons. Such a decision only provides a short term solution to a problem that ultimately gets worse and comes back to bite even greater. Technologies such as BIM, Mobility, Analytics, and a suite of ISO standards represents a coming of age for rail systems asset management. They are transforming the rail sector and are helping to drive a long term approach to maintenance with benefits. One that is now allowing staff to do more with less whilst allowing them to improve the asset reliability, availability and system safety.

2017 – March – D’Cruz – Do we have the backbone to support emerging technologies?

Author(s):
Date presented: February 25th, 2017

Malcolm D’Cruz M.E. Mechatronics
 Public Transport Authority of Western Australia David Lim  MSc. Telecommunication Management UXC Ltd – A CSC Company Railways are always increasing the number of network services to cope with emerging technologies. The success of Communication Based Train Control (CBTC) depends on the ability of the backbone communication system to guarantee high bandwidths and reliability. Thus the traditional railway communication network is gradually moving towards a carrier grade network servicing both internal as well as external clients. The aim of this paper is to show how Software Defined Networks (SDN) adopted by telecom service providers as a common platform for all network services can benefit the railway networking environment to cope with constantly emerging technologies.

2016 – Sept – Cox – Level Crossings, When is enough, enough?

Author(s):
Date presented: January 4th, 2017

Introduction Level crossings represent high risk exposure for railway operators. Obligation for engineers and railway operators is to ensure level crossing risks are seen to be reduced So Far As Is Reasonably Practicable (SFAIRP). Grade separation is best solution but how can we ‘sweat’ level crossing assets? Once you have ‘lights, booms and gongs’ what then? Road complexity, number of cars, type of traffic, frequency of trains all increase risk What else can we do?
