Cost-effective redundancy for ethernet train communications using HSR

In this work a novelty use of the High-availability Seamless Redundancy (HSR) in the Train Communication Network (TCN) is presented. Nowadays, the 10 years old TCN standard is being renewed toward an Ethernet-based solution, but it is necessary to accomplish some special restrictions for such a critical application. The HSR standard can help solve the redundancy required in train communications.
