`Abstract
`
`The Eurocab project defines an automatic train protection (ATP) architecture which
`supports different signalling systems. To this purpose, ATP devices on-board a
`locomotive are connected by a serial databus. Due to the real-time requirements, this
`bus has
`to guarantee
`fast and deterministic response
`times. Due
`to safety
`requirements, this bus has to provide a high data integrity. Since the bus is not
`considered able to be trusted, safety applications have to implement a safe user layer
`on top of the usual bus protocols.
