fantastic work Ive been a fan for a few years!

Maybe a general "train to newcastle / Birmingham" map like this? https://map-shop.co.uk/wp-content/uploads/2024/11/ms00004-uk...

A wimbledon tram one could be good and might appeal to the richer demographic ( im not sure ). https://www.croydon-tramlink.co.uk/info/gen/images/RouteMap....

Finally an overnight sleeper train only (europe) could be good: https://media.timeout.com/images/105981668/image.webp

Just suggestions I have no idea if these are good ideas.
