RedTrain is an Australian wholesale carrier who is experienced in the design, deployment, and management of fibre network infrastructure. RedTrain designs, builds, operates, and maintains fixed-line access and fibre-based telecommunications networks, much like NBNCo does. RedTrain operates an open-access telecommunications wholesale service in Australia and has been building fibre infrastructure. In the open access system, internet service providers (also known as retail service providers) such as Occom purchase bandwidth from wholesale providers (e.g., RedTrain) and deliver internet services to end users.
