The queueline TVs have actually all been replaced/fixed earlier this season as I've seen a few photos of them working, hence why the news audio has also returned playing in the queue.
However for some reason, they're never on? I've never seen them on since. Strange.
I agree the area could do with some TLC, would be great to see all the effects return as it definitely makes a difference. Personally quite like the area music how it is, however it would great for the sound effects to return. There used to be loud sound effects as the train passed certain areas, such as the tower at the last inversion.
Agree the station music is very dull and boring though, could definitely do with a change there.
