Modelling and Hierarchical Control of CBTC
2018 6th International Conference on Control Engineering & Information Technology (CEIT), 2018Over the last decade, the railway industry has a great evolution about signaling system and there is more orientation from the standard railway signaling system to the communicationbased signaling system day to day. Communications-based train control (CBTC) is a very flexible and useful approach to check train activity and track operation.

Modeling the CBTC Railway System of Siemens with ScOLa
International Journal of Intelligent Transportation Systems Research, 2017Considering their increasing complexity, industrial systems are, in general, specified in a natural language. In railway systems, the design phase results an ambiguous and laborious system specification. The objective of this paper is to present ScOLa, a formal modeling language based on scenarios and built for railway system specifications.

ASME/IEEE 2007 Joint Rail Conference and Internal Combustion Engine Division Spring Technical Conference, 2007
The recent progresses in mobile telecommunications technologies have allowed railway telecommunications technology to go a step forward, and, in the same way, the railway control systems. In this sense, while the mobile telecommunications technology evolved from the first generation of analogue mobile communication systems to what is known today as B3G

CBTC Field Test and Commissioning
2015 Joint Rail Conference, 2015Communications-Based Train Control (CBTC) technology is the most advanced train control system for urban railway infrastructures. It is very different from conventional relay based signaling systems and more complex than most cab signaling systems. CBTC functions are numerous, highly complex with customized details for each project.

The channel emulator for CBTC wireless communication system
2010 7th International Symposium on Communication Systems, Networks & Digital Signal Processing (CSNDSP 2010), 2010A channel emulator working at 2.4 GHz ISM band related to tunnel environments for testing communication based train control (CBTC) wireless system is introduced. Based on three mechanisms, path loss, multi-path fading and Doppler frequency shift, the multi-port channel matrix is adopted to construct a multi-input and multi-output channel environment ...
