The invention concerns a system for distributed interlocking of track field objects of a railway network comprising a central automatic train supervision system (2) comprising a wireless communication interface (6) adapted to communicate with an automatic train control system (30) onboard of a train, and at least one field object controller (40), each field object controller (40) being connected via a communication link to at least one track field object (50, 52, 54) and being configured to receive status information from said track field object and to command a change of status of said track field object.The automatic train supervision system comprises at least one processor (4) configured to generate smart contracts (70), a smart contract comprising at least one block of logical objects, in the form of Boolean equations, each logical object being representative of a track field object (50, 52, 54) associated to at least one section of track to be travelled by said train, send the generated smart contracts for execution to at least one field object controller and to the onboard automatic train control system of a train. Each smart contract (70) comprises non-tamperable chaining information indicating an order of successive execution of blocks of logical objects. Each of the onboard automatic train control system and field object controller(s) comprises a processor (40, 42) adapted to implement a smart contract execution engine (76,80).
