The new Museum's site also has a very cool view through a window, but it's a view of the passing trains [underground], because historically that building (one of London's markets) had a freight service and of course there's no room to move a railway line under London so even though it hadn't needed a freight service for decades the passenger service over the same rails still exists and you will be able to wave to surprised (if they haven't taken that route before) passengers from inside the museum.
A friend lucked into (there's literally a lottery for popular sites) tickets for the new site in Open House London 2024 and the window existed but wasn't really set up for tourists yet of course.
I'm terrible at keeping secrets so, it was probably a bad idea to let me go on the tour, or, perhaps we should try to have fewer secrets so that I'd remember ?
Well, not quite, these aren't tube trains, they're ThamesLink trains, so it would be a mainline railway station, not a tube station, albeit underground. And they already have more appropriate stops in London.
