Thank you, Mr. Chair, for the opportunity to provide further details on the technology that is behind the efficient operation of any high-speed railway.
All railways need to operate according to a set of rules that ensures the safety of the passengers, trains, and everything in the immediate vicinity of the railway in addition to the actual service provided by the railway. These operating rules are embedded in what is called the “signalling and train control” system, usually shortened to “signalling”.
High-speed railways in Europe use an implementation of signalling that is known globally in the industry as the ETCS, or European train control system. ETCS has the advantage of being a universal signalling system that can be used for all modes of train service in addition to such high-speed operations as commuter and freight operation. ETCS enables the transmission of information from along the track to the train, allowing the computerized on-board equipment to calculate and monitor continuously the maximum-operation speed of the train in connection with a graphic display for the driver in the cab of the train.
ETCS brings considerable advantages to railways--for example, increased capacity on existing lines as a result of reducing headways, or the space between trains; higher speeds up to a maximum of 500 kilometres per hour; reduced maintenance costs due to less equipment; and, as well, improved safety.
There are several levels of ETCS, depending on the complexity of the requirements of the railway's operation. The fundamental building blocks of ETCS are well defined, comprising a warning indicated to the driver when approaching a signal, a train stop function at signals, or a supervised braking curve in front of signals. These are selectable by the railway, depending on the level of supervision required.
Most importantly, at all levels of ETCS, the on-board computer compares the train's speed with the maximum speed allowed on that section of the railway, and applies the brakes automatically if the speed is exceeded.
The multiple levels of ETCS allow the optimized application under different operational and technical conditions for a specific line or subnetwork. Because trainborne equipment is downwards-compatible, trains can operate seamlessly on the whole network. A high-speed train could actually transfer to commuter or freight lines in certain instances. In some systems, an increase in train services of up to 40% has been achieved.
ETCS levels one and two are now in operation on all kinds of railways, from high-speed to conventional to commuter and regional lines, covering high-density and low-density operations. By now, thousands of kilometres of ETCS track and on-board equipment are either in service or being installed. A total of 35,000 kilometres worldwide has been projected to be equipped.
It's interesting to note that 50% of this track is located outside Europe, in countries such as Mexico--and hopefully here in Canada. This demonstrates the global acceptance and performance of ETCS.
Suppliers and all global customers alike are working together to maintain a common framework to ensure stability of ETCS today and in the future. A well-defined change control management process maintains the standard, using feedback from all stakeholders. This is a continuous process to keep ETCS stable while still being able to be improved.
From the beginning, one intention was to open the market with ETCS so that interfaces were standardized, which fostered competition between several suppliers of ETCS trackside and trainborne equipment. Competition is now well established, safeguarding cost-effective and efficient solutions for the benefit of railways worldwide.
This is certainly relevant for project tendering and implementation. Additionally, it guarantees a long lifespan for the system solution, because more than one supplier is able to deliver components.
In summary, the signalling technology exists today that can safely and reliably operate high-speed rail, as demonstrated in countries such as France, Germany, Spain, and Japan. Thales looks forward to participating in the building of Canada's first high-speed railway, much like we participated in building Canada's first driverless metro system in Vancouver in the eighties.
Thank you.
