The objective of this WP6000 is to prepare, coordinate and perform the train experimentation in MOWGLY. The rail sector is one of the target sectors in this project with some special characteristics that differentiate it from aviation and maritime sectors, like the lack of coverage in tunnels or the possibility of having a terrestrial return link. For this purpose, a team led by INECO will prepare a series of tests and experiments using high-speed rolling stock in a real environment. The experimentation will be performed on high-speed trains from RENFE, the Spanish leading train operator.
