Bogie control and safety systems are an essential part of safe train travel, as these systems continuously monitor and guard the stability of a train carriage. As with most systems, the firmware and software of the components must be updateable in order to install bug fixes, add new features and apply security patches. For train systems, especially the safety-critical part, this often meant locating the train, sending a technician to it and installing the update locally. This paper presents the practical experience of enabling remote and reliable firmware and software updates for the different devices that are part of an industrial bogie control and safety system.
