Fuelled by demand for greener travel options, new routes are now once again snaking across the continent - including the sleeper from Brussels to Berlin that Sky News ClimateCast presenter Tom Heap finds himself on.

In this episode, Tom speaks to Adalbert Jahnz, the European Commission's transport spokesperson, about how sleeper trains fit with the EU's green ambitions, and to a man invested in the success of this mode of transport - Chris Engelsman, co-founder of European Sleeper.
