In contrast to classic train protection systems where
most of the safety measures are built into the rail infrastructure,
future versions of the European railway safety
system ERTMS (European Railway Traffic Management
System) require trains to check their own safety. One of the
safety measures is the train integrity check, which checks
whether all carriages are still in the train. The check
has to be completed in a certain amount of time. This
paper presents an overview for communication in such
an integrity system, based on a wireless sensor network
(WSN). Because a WSN with nodes in each carriage has a
linear structure, existing communication protocols which
assume a mesh-like topology do no suffice. Simulation
shows that the proposed communication is feasible and
has the necessary (soft) real-time properties to complete
an integrity check in time. The protocol, based on the
IEEE 802.15.4 network stack, is implemented and tested
