  Railway embedded software - Safety Integrity Level(SIL) complying with IEC61508 and EN50128 

  http://www.cecube.co.uk/software/software.htm

  BESPOKE SIMULATION Software has been employed by the railways industry, and in traction engineering in particular, since mainframes with paper tape and card readers became commonplace in the late 1960's. ... At that time Universities and large organizations monopolised the scare computing resources. While companies were writing their own COBOL business programs, academics and students applied the scientific based FORTRAN language to research problems. This provided the opportunity to replace restrictive analogue simulations with digital computer simulations of greater complexity. Circuit analysis and behavioural modelling on a large scale was possible - DC motors, chopper circuits, thyristors. Simulation first supported theoretical analysis, and then extended it beyond what was analytically feasible. Coding was largely a process of trial and error, often with poor or no structure. However, undoubted excitement and motivation was born on the vision of ever increasing computing capacity, giv   [More...] [Less...]

A well-known problem related with totally floating systems is that the touch potentials can be dangerously high. In order to reduce the voltages on rails, several devices exist. Most of these devices allow a direct connection to earth when a certain voltage threshold is exceeded. In this paper, the working principles of these devices are given and the effect of certain parameters related with these devices on the minimum achievable touch potentials is   [More...] [Less...]

  Railway Technology Consultants Limited.... Railway Technology Consultants Limited was launched under its present name in January 2006. It brings together a wealth of experience in railway EMC consultancy ... and railway EMC & Vibration testing. The previous company A Hines Engineering Limited began trading in 1998 and was born out of experience gained within the engineering and research functions of British Rail. Specialist knowledge in the area of railway electromagnetic compatibility (EMC), and in particular Signalling & Traction compatibility and EMC & Vibration testing, forms the foundation of this company. read more ... EMC & Vibration Testing... All new or modified electronic/electrical equipment supplied to the railway industry must go through EMC approvals as required by UK law to comply with the EEC Directive on EMC 89/336/EEC and to demonstrate that it sufficiently electromagnetically robust to survive in the railway environment.   [More...] [Less...]

  Informit - The Use of Supervisory Control and Data Acquisition Systems in Electric Traction Power Systems (Engineering Collection) 

  http://search.informit.com.au/documentSummary;dn=461090913968582;res=IELENG

  Abstract: A supervisory control and data acquisition (SCADA) system is an essential component of a modern electric traction power system. The functions of a SCADA system and its application to power systems ... are described. The four main subsystems of a SCADA system are the computer subsystem, the man machine interface, the data transfer subsystem and the system software. Each of the subsystems and its functions is outlined. The SCADA systems used by Queensland Railways in railway electrification power systems are outlined and some of the facilities in these systems are presented. (620kb) To cite this article: Welch, JA.

  ONE BREAK POINT IS ENOUGH: TRACTION POWER SIMULATION IN PORTLAND 

  http://pubsindex.trb.org/document/view/default.asp?lbid=700195

  Traction power computer simulation software has changed in the last 20 years. The tool has evolved from simpler, DOS-based, energy management software to detailed, Windows-based, user friendly, analytical ... software that can accurately model train performance, predict train voltages, and produce a train voltage profile for an entire rail system. Traction power computer simulation software is now used as a comprehensive design and analysis tool in the development and upgrade of the traction electrification system (TES) for modern rail systems. The software allows the designer to analyze the existing or proposed traction power system under various operating conditions including contingency outage conditions. The designer can also optimize the size and location of the traction power substations as well as the number and size of important components of the overhead contact system (OCS) such as wire, feeder cable, and parallel conductors. As part of the Interstate MAX Light Rail Project in Po   [More...] [Less...]

  Railroad Simulation Journal 

  http://woodbrdge.tripod.com/tsc/

  Formerly Train Simulation Craftsman Topic: Welcome! Railroad Simulation Journal by Brian Eckard W elcome to the first volume of our brand new Rail Simulation Journal! This blog replaces the Train Simulation ... Craftsman magazine blog. At the end of 2007 I made a decision that as I move forward with my new life, it was time to put some things from my past behind me. And, I decided that my magazine should be one of those things (from my past) that needs to be retired. I have also decided to put on hold offering for sale e books containing reprints of the TSC volumes that have appeared in recent years on this blog site. I do intend on making these e books available in the future, but not the foreseeable future. At this point in my life, I don't want to get tied down with running my own business. So, I have decided to put those things on hold until a more opportune time presents itself. With that said, what is this blog site going to become? And, what does this new name mean? Let's start with   [More...] [Less...]

  Technology Consulting for Traction Solutions Virgin's Tilting Pendolino on WCML - London to Glasgow at 125mph and faster This site is dedicated to technical discussion and issues related to electric / ... electronic traction drives and railways. Taking the train above as an example, critical railway standards required expert EMC compliance demonstration before the Alstom manufactured Pendolino trains could enter UK passenger service. Some of the analytic and simulation safety methodologies are described, including Cecube Components , a unique software set for traction drive and train simulations. Now available - the concluding topical article about on railway networks. TOP-FACE is a generic EMC modelling system (graph below), using inputs from track layout, lineside system geometry, the position of track circuits and trains, plus geographical inputs from sources like Google Earth & Maps.
