BS EN 50668:2019 PDF Download

BS EN 50668:2019 is a standard that outlines the minimum functional requirements for signalling and control systems in non-UGTMS urban rail systems. These systems operate either through line of sight or with intermittent train control using automatic interlock signalling. It is important to note that this standard does not apply to urban rail systems that are part of an urban traffic control system, but it may be interfaced with such systems.

The main purpose of this standard is to provide a basic framework of functional requirements that can be used as a starting point for defining more specific requirements for urban rail signalling and control systems. It aims to ensure interoperability and compatibility among different systems by establishing a common foundation.

It is worth mentioning that this standard is not applicable to command and control systems that utilize continuous data transmission and continuous supervision of train movements by train protection profile. These systems are already covered by the EN 62290 series.
