A train diagnostics system 1 has an on-board control unit 2 linked by a local area network (LAN 30, Fig.3) to interfaces (31, 33, 35, Fig.3) to train systems and sensors (32, 34, Fig.3); a wireless interface (11, Fig.2) for transmitting diagnostics data from the control unit; and a ground-based server 3 which receives the diagnostics data and processes it to generate diagnostic reports. The wireless interface transmits the diagnostics data in multiple channels, including a live data channel and a backfill data channel for data not successfully transmitted on the in real-time channel. There is a separate software process for each channel, and the real time channel process automatically hands over to the backfill channel process a message for which a positive acknowledgement has not been received when transmitted on the live channel.
