With quick inhabitants explosion, enhancing rail transit velocity and capability is strongly fascinating world wide. Communication-based educate keep watch over (CBTC) is an automatic educate keep watch over process utilizing excessive means bidirectional train–ground communications to make sure the secure operation of rail cars. This e-book provides the newest advances in CBTC examine. The contributed chapters from top specialists within the box hide diversified features of modelling, research, layout, checking out, administration, deployment, and optimization of CBTC systems.
Advances in Communications-Based teach keep an eye on Systems starts off with the heritage and evolution of teach signaling/train keep an eye on platforms. It introduces the most positive aspects and structure of CBTC platforms and describes present demanding situations and winning implementations world wide. next contributed chapters talk about such key examine parts as
- Nondestructive checking out strategies that may be hired to examine rails and fastening parts
- New instant channel modelling thoughts for underground tunnels and viaducts
- Advanced instant verbal exchange structures to enhance CBTC verbal exchange availability
- Schemes to combine teach keep an eye on and train-ground communications by means of modelling the keep watch over procedure of a bunch of trains in CBTC as a networked keep watch over system
- Use of cognitive keep an eye on to enhance teach regulate functionality, contemplating either train–ground conversation and teach control
The booklet comprises many helping illustrations and tables besides a beneficial set of references on the finish of every bankruptcy. With this booklet, researchers and practitioners can be well-equipped to develop the examine and improvement during this vital field.

Another difficulty for projects on new lines is that the other systems, which also require track access, may not be working properly during the CBTC tests. In particular, the rolling stock may be ready for CBTC tests but not for revenue operations, and the remaining rolling stock issues may affect CBTC tests if a train becomes stranded during testing. 2 Migrating an Existing Line: Brownfield Project In large cities where the railway infrastructure was created decades ago, the cost of building a new line is very high and the time to create a new line is very long.
CBTC includes redundancy and built-in diagnostic systems which report the status of most equipment to the automatic train supervision (ATS). These functions are also possible with other types of train control implementations. Testing Communications-Based Train Control ◾ 19 ◾ Reduced maintenance cost. CBTC has less equipment than conventional signaling systems, in particular on the trackside. ◾ CBTC has been deployed for more 30 years all over the world and is now a proven technology. 2 Cons of CBTC CBTC technology also comes with several challenges for transit agencies: ◾ Initial investment cost of deploying the technology may be higher than other types of train control.
For data communication interface tests such as interface to an SSI, there may be a difference between the transit agency that prefers to test every bit and the CBTC suppliers who want to only sample the bit map. The argument from the CBTC suppliers to perform only sample tests is that each bit was previously tested in the factory. The argument from the transit agency is that the factory tests are not witnessed and the configuration files may have changed since the factory tests. In an ideal world where every change is tracked and retested in factory, there is no need for testing all external digital interfaces.
