All the elements which make up the wayside signaling infrastructure play a vital role in system optimisation and passenger safety. Engineering and preventative maintenance servicing for CITYFLO solutions can be planned efficiently and in advance with EBI Tool Design and Maintenance. CITYFLO signalling is a CBTC system designed by Bombardier Transportation. It makes use of bi-directional radio communication between trains and.

It is important to mention that the occupancy calculated in these systems must include a safety margin for location uncertainty in yellow in the figure added to the length of the train. This section needs to be updated.

This article needs additional citations for verification. EBI Switch point machines are designed to provide increased availability on the rail network and cost-effective maintenance of the complete turnout. Train conductors will be located aboard the train because other parts of the routes using the Queens Boulevard Line will not be equipped with CBTC.

Since every block is a fixed section of track, these systems are referred to as fixed block systems. Views Read Edit View history.

Communications-based train control

CBTC systems normally have less wayside equipment and their diagnostic and monitoring tools have been improved, which makes them easier bombardiwr implement and, more importantly, easier to maintain. Its state-of-the-art features include:. Application of railway signals Cab signalling North American railroad signals Railway semaphore signal. The EBI Screen control room can connect to auxiliary systems.

CBTC systems are modern railway signaling systems that can mainly be used in urban railway lines either light or heavy and APMsalthough it could also be deployed on commuter lines. In addition, the unique features of Bombardier’s CBTC solution means it can bombardiee used as an overlay system which results in no disruption to passenger services during migration and upgrades.

The EBI Cab onboard ATC equipment includes the functionality to assist train drivers during a journey by optimizing their driving style with a view to bombardiet energy. By using this website without disabling cookies, you agree to our use of cookies.

Meeting the capacity challenge

When transmitting a MA, it is the end of the last section given in the MA [6]. Wealth of experience Bombardier is a market leader in CBTC technology with our moving block CITYFLO solution in delivery or in operation on 40 lines globally, from automated people movers to fully automated, high-capacity lines.

The EBI Screen control room also provides train regulation for the system.


Moving Malaysia — fully-automated rail control for Bombardeir Lumpur. These systems are suitable for the new highly demanding urban lines, but also to be overlaid on existing lines in order to improve their performance. Retrieved January 9, Phoenix Sky Harbor Airport. This technology, operating in the 30—60 kHz frequency range to communicate trains and wayside equipment, was widely adopted by the metro operators in spite of some electromagnetic compatibility EMC issues, as well as other installation and maintenance concerns.

The transmission of this data is made possible by the use of both the fibre-optic transmission system and the radio equipment. So, for clarity and to keep in line with the state-of-the-art solutions for operator’s requirements, [5] this article only covers the latest moving block principle based either true moving block or virtual blockso not dependent on track-based detection of the trains [2] CBTC solutions that make use of the radio communications.

The information needed from the track for the normalization of position errors for the system is passed to the train through norming point balises located in the middle of the track at various points.

A CBTC system is a “continuous, automatic train control system utilizing high-resolution train location determination, independent from track circuits ; continuous, high-capacity, bidirectional train-to-wayside data bombardir and trainborne and wayside processors capable of implementing Automatic Train Protection ATP functions, as well as bombardire Automatic Train Operation ATO and Automatic Train Supervision ATS functions,” as defined in the IEEE standard.

Cityflo CBTC – Wikipedia

This results in a reduced headway between consecutive trains and an increased transport capacity. If so, there is an increased risk of a single point of failure that could boombardier service over an entire system or line. Edmonton Light Rail Transit. EBI Screen control room.

Tokyo Metro Hibiya Line. Bombardier Transportation Rail Control Solutions, Which way to go? Finally, it is important to mention that the CBTC systems have proven to be more energy efficient than traditional manually driven systems. Retrieved from ” https: The higher the GoA, the bombqrdier the safety, functionality and performance levels must be.

The EBI Drive semi-automatic train operation ATO system which is part of the EBI Cab onboard equipment, fully optimizes the capacity of the system as the train proceeds along the line at a safe distance from other trains.


In principle, CBTC systems may be designed with centralized supervision systems in order to improve maintainability and reduce installation costs. The primary risk of an electronic train control system is that if the communications link between any of the trains is disrupted then all or part of the system might have to enter a failsafe state until the problem is remedied.

In a moving block system as shown in the second figure, the train position and its braking curve is continuously calculated by the trains, and then communicated via radio to the wayside equipment.

We have many years of experience in allocating the appropriate resources during the different phases of a project and successfully delivering high-quality solutions in a limited timeframe. Both of them form what is usually called ‘Footprint’. The IRT Flushing Line runs trains with eleven cars, though they are not all linked together; they are arranged in five- and six-car sets. Discreet and safe point machines.

Since train-to-wayside communication is provided via two-way radio, the exact position of the trains is known at every moment. Some of the top 30 world’s busiest metros in terms of annual passenger rides [1] utilise a CBTC bojbardier.

Traditional signalling systems detect trains in discrete sections of the track called ‘ blocks ‘, each protected by signals that prevent a train entering an occupied block. The system communication network provides a private, secure and redundant communications path between the wayside and the onboard ATC equipment. The moving block ATP system has an American safety certification bombadrier public bctc. The train speed is constantly monitored by the system and if necessary, the EBI Cab system automatically initiates braking to keep the train at a safe speed.

Bombardier designed and supplied the electrical and mechanical systems for the Neihu Line — an extension of the existing Taipei Metro Line 1.
