CBTC systems have increasingly become the standard technology for urban rail train control systems and have been deployed both on newly built lines and when modernising existing underground railway commuter rail lines. However, the implementations from various vendors differ, for example, with respect to the internal and external interfaces, moving block algorithms, zoning concepts and integration with the peripheral systems....
