Hello Anton! I really enjoy watching your videos because I am also a public transport enthusiast, especially the metro. I'm from Portugal, from Lisbon and I saw and saw the videos you made here on the Lisbon metro in 2018 and 2019. There are metro routes that I would like you to do, including a stop at a station that in those two years was closed and for about 1 year and a half reopened. It's the Arroios station on the green line. if you came back here i would like you to make a video showing that station. big hug and continue your work. 😊😊
