Short ad and video #1, click white arrow.. Lengthy interview with head of local public transport and lots of aerial shots of operations and station activity. If I understood correctly not all stations have big enough platforms for those partitions.
The cars looks to be stainless(?)with nice red stripes and strong enough to support overhead equipment as well as pantographs. No litter and no homeless and everyone wearing masks but jammed together.
Muito obrigado e bom dia.
