**7. Conclusions**

The W40 concept is able to yield significant operational and logistical advances, yet it relies on proven technologies. The concept can be scaled depending on the intended application, ranging from communication to full automation of wagon movements.

While the concept yields operational and economic benefits, it is at the same time a means of reducing the manual labour required, a further contribution to the future of the rail freight system by providing meaningful and safe jobs to future railway workers.

W40 class 2 was implemented as demonstrators in the funded project.
