I have the London board in my living room. It's one my favorite parts of the house. Can't recommend it enough.

Wow this is presented exactly the same as the flight data led display. It is odd that the advertising method and the comments are similar to the previous.

Train Trackr is great, and the weather one is also good too.

If you are less into trains (heresy) but still want to look at unusual maps https://raildar.co.uk/map/KGX is your place to go. its a live junction schematic of any train junction in the UK.
