Autonomous train

A ground-breaking global autonomous train development project in Finland is moving on to its test phase. The aim of the initiative is to create completely new railway transportation services and to even double the amount of railway transport. The initiative, led by Finnish Proxion in conjunction with around 20 other tech organisations, innovates an agile, low-emission transportation concept for large industrial enterprises. In the future, aim is to also bring autonomous passenger traffic to the rails.
