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.

Bombardier designed and supplied the electrical and mechanical systems for the Neihu Line — an extension of the existing Taipei Metro Line 1. It also enables the wayside equipment to define the points on the line that must never be passed by the other trains on the same track. Bojbardier mode operation for Kuala Lumpur. From the signalling system perspective, the first figure shows the total occupancy of the leading train by including the whole blocks which the train is located on.

Communications-based train control

Although this is a rather common bombarduer for resignalling projects, it can negate some of the cost savings of CBTC if applied to new lines. Rail control services solutions. Movement Authority MA is the permission for a train to move to a specific location within the constraints of the infrastructure and with supervision of speed [6].

Application of railway signals Cab signalling North American railroad signals Railway semaphore signal. Its state-of-the-art features include:. Some of the top 30 world’s bombarrdier metros in terms of annual passenger rides [1] utilise a CBTC system. These points are communicated to make the trains automatically and continuously adjust their speed while bkmbardier the safety and comfort jerk requirements.

From automated, driverless systems to intercity and high-speed solutions, everyday, our systems transport thousands of passengers quickly, reliably and safely. Views Read Edit View history. If cbt outage is permanent some sort of contingency operation must be implemented which may consist of manual operation using absolute block or, in the worst case, the substitution of an alternative form of transportation.


Communications-based train control (CBTC)

The information needed from the track for the normalization of position errors is passed to the train through norming point balises located in the middle of the track at certain points. Besides, the bomvardier distinguishes between the implementations performed over existing and operative systems brownfield and those undertaken on completely new lines Greenfield. Unsourced material may be challenged and removed.

Higher levels of automation. These balises give an exact position bombardie the train as it passes and allows the train to normalize its position, reducing the position error.

Cityflo CBTC – Wikipedia

For instance, with the advent of modern electronics it has been possible to build in redundancy so that single failures do not adversely impact operational availability.

This bombarsier a modern computer-based control and supervision system allowing the cbhc to give commands through a mouse or keyboard, with the facility to have the position of the vehicles and optional wayside objects shown on both normal display screens and large rear projection screens. Trains report their position via radio, and a wayside signalling system provides movement authorities to the trains via a radio link.

A test track was retrofitted in ; the line’s other tracks will be retrofitted by the early s. EBI Switch bombatdier machines are designed to provide increased availability on the rail network and cost-effective maintenance of the complete turnout.

From Wikipedia, the free encyclopedia. By means of the CBTC systems, the exact position of a train is known more accurately than with the traditional signaling systems. Bombardier is also an expert in providing fully integrated turnkey transportation systems from power supply to automatic fare collection and from passenger information to depot systems.

Since train-to-wayside communication is provided via two-way radio, the exact position of the trains is known at every moment. Phoenix Sky Harbor Airport. Transit lines using the Cityflo system as of February 26, include the following: Walt Disney World Monorail System.


Moving people worldwide For years, Bombardier has been developing, engineering and installing advanced rail control systems.

Centralized traffic control CTC for the efficient monitoring and control of rail traffic Integrated human-machine interface IHMI Train identifier system and routing automation Timetable management Optimized automatic train regulation ATR Authority management Maintenance and diagnostic functions including playback functionality Power system interface, control and supervision Publishing schedule information to a third-party system. There is no need for any physical vehicle detection system such as track bombardoer or axle counters which reduces the overall wayside equipment required and eliminates additional maintenance costs.

The system is used for automatic running of trains on segregated tracks.

Our diagnostics systems can also help to identify unexpected occurrences such as door failures or overshoots at stations that will highlight potential maintenance issues. EBI Cab systems may not only generate savings in energy consumption, but also ensure that trains arrive on time.

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. We have updated the terms of our Privacy Statement to reflect our commitment to conducting business in compliance with data protection laws wherever we do business. Moore, Railway Age, The solution offers tailored after-sales support and training. Despite the difficulty, the table below tries to summarize and reference the main radio-based CBTC systems deployed around the world as well as those ongoing projects being developed.

Retrieved from ” https: Metros and other railway systems are able to improve headways while maintaining or even improving safety.

Track-to-train communication is achieved via state-of-the-art wireless technology to provide bi-directional communication. 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.
