Lui Gough has been researching the Australian railroad system’s new digital radio system and has posted detailed observations:
As a radio enthusiast, and highly observant public transport user, I’ve made many notes about the deployment of the new Digital Train Radio System (DTRS) sites. This new system is based upon GSM-R in the 1800Mhz band, and is intended to replace the end-of-life Siemens Metronet analogue/digital hybrid trunked network that is currently in use and installed in 1997. From what I’ve been told, Huawei base stations are being used for the deployment.
