I've had an interesting few days in Paris. It started with meetings of UIC - International union of railways #UICrail International Rail Research Board hosted by Artur Fojud. And it moved on to an event at Université Paris-Saclay Institute for Sustainable and Digitized Railway Infrastructure hosted by Pierre-Etienne Gautier and Pierre Jehel. It was a pleasure to meet fellow speakers Barbara Grau, Mathieu Arquier and Marion Berbineau. A common theme was around collaboration between academia and industry on rail research and education - learning lessons from experience within countries, from bilateral international collaborations, from coordination at a European level, from coordination through orher regional competency hubs and even at a global level. There are obviously local differences in emphasis but the challenges/opportunities are more similar than different and we will achieve more by collaborating more. I think the main obstacles are awareness and time rather than willingness or money so it would be wonderful to make such collaboration more time-efficient. Another theme was around all aspects of diversity. I am more convinced every day that multidisciplinary teams of people from all parts of our industry are key to many of its challenges/opportunities. I needed no persuading about the contribution which can also be made by improved gender balance (and diversity more generally) but I learned more about the European version of Britain's Women in Rail which is helpfully called Women in Rail.

Yesterday, RATPgroup and Ile-De-France Mobilités conducted the final trial run for the extension of Line 11. This is one of the largest projects currently undertaken by RATP, both in terms of scope and impact on commuters, with the key change being a drastic improvement in convenience and management of passenger journeys. The comprehensive overhaul of Line 11 includes the addition of 6 new stations and the modernization of 10 of the existing stations, in order to improve accessibility for those with reduced mobility. The current stock of trains will be replaced by M14 trains, fitted with cutting edge technology to improve access and comfort for passengers. This transformation to the system will also enable streamlining of passenger journeys, a reduction in commuting time from the suburbs to the center by half and connection to the metro lines for an additional 80,000 daily passengers. Significant changes indeed! I'd like to extend congratulations to those involved in this feat of technical and operational expertise.

European Railway signalling are different from a country to others  Railway Administrations  OBB- Austria NMBS/SNCB - Belgium SBB -Switzerland DB AG Germany RENFE Spain SNCF - France BR Great Britain FS- Italy CFL- Luxembourg NSB- Norway NS -Netherlands BV- Sweden   Basis of signalling systems    The aim of all railway signalling systems is to prevent collisions and derailments whilst allowing trains to travel at whatever maximum speed is allowable by the characteristics of the line and the vehicles that run on it. This can be achieved either by giving orders to drivers by visual means, typically coloured lights or semaphore arms, or by a visual and/or audible display in the driving cab. In the latter case, the signalling information, having been transmitted to the train, can also be used to enforce compliance should the driver fail to respond to cautionary or danger signal aspects. It thus follows that signalling systems must be designed to be fail-safe. This means that the failure of any component or subsystem must result in a default state which ensures safety in all circumstances. Systems and equipment are therefore designed, manufactured, installed and maintained with safety as the foremost consideration, as is required by the various railway administrations and their respective governments. Other facilities and management systems are linked with the signalling, for example train identification, automatic route setting and train recording, but these must never be allowed to interfere with the safety embodied in the signalling system. Anything less sophisticated than a fully automatic railway needs people to run it and human failures must also be taken into account in designing a safe signalling system. Of particular concern is drivers passing signals at danger and this is being addressed through various forms of Automatic Train Protection (ATP). The system must also be designed as far as possible to eliminate or reduce the effects of failures or malpractices of other members of staff, such as signalmen and signal maintainers. However, when the signalling system does fail, trains must still be enabled to move, albeit at reduced speed. The effects of a failure and the process of restoration to normal working need careful consideration, together with adequate training of all relevant personnel. Key elements:  There are a number of key elements in the design of signalling systems which are vital to the manner in which they achieve the required degree of safety. They are: • train detection, by track circuits and axle counters; • control and detection of track elements, such as points, swing nose crossings and switch diamonds; • method of interlocking points and signals; • indications to the driver by lineside signals or cab signalling; • enforcement of signal controls on the train with train stops or ATP; • braking characteristics of the rolling stock using the line. To be continued for the details of each country ....
