Not really, no. The trains running from those stations are mostly newer, cleaner, and quieter. Especially dedicated lines such as the cross river Jersey-WTC line which drops you off in a luxury apartment area in Jersey.
You don't give the rich enough credit. They will make sure to cater to themselves as much as possible.
Plus the platforms are kept especially clean and polished, and any aesthetical defects such are cracks are solved quickly. The walls are usually tiled as well, the ceilings finished, and the rails aren't left bare.
You can even see a nice group of piggies!
It also didn't always look that way. The oncoming wall used to be unfinished an unsightly, but they tiled it up and added some art for decoration. This is how it used to look, the first picture shows the finished wall.
Because that's not British food? That's food that was brought over from colonized peoples? That's like going to a truly authentic Japanese restaurant in Brazil and saying, "That was the best Brazilian food I've ever had".
Also that second one looks... interesting. Its nice to know that seasoning is still a mystery to the British isles.
