London Underground - anywhere actually haunted, or just urban legend?

Alright, so I've read loads about supposedly haunted Underground stations - the woman on the Circle Line, St. Paul's, various other claims. I take the Tube daily and I've never experienced anything unusual, but I'm curious if there's any genuine documentation of hauntings versus just folklore.

The stories always seem half-remembered and vague - 'my mate saw a ghost woman,' that sort of thing. I'm wondering if anyone on here has done proper research into specific incidents, deaths at stations, or documented paranormal activity.

Alternatively, are there particular stations with stronger reputations than others? Worth doing an informal investigation on?

Most Underground 'hauntings' are urban legend, but there have been documented deaths and accidents over the 150+ years of operation. St. Paul's was heavily damaged in WWII - people dying in bombing raids, etc. That's where the haunting reports come from. Real history, more interesting than ghosts.

Because they ARE half-remembered. People experience strange things on the Tube (odd lighting, tired perceptions, stressed mental state) and construct ghost narratives afterward. Confirmation bias in action.

Actually there's decent historical documentation of the King William Street branch, which was abandoned. People have reported activity there - though access is restricted so hard to properly investigate. Worth reading about the station's history - it's properly eerie even without supernatural elements.

I've investigated Bond Street and Bethnal Green. No paranormal activity detected, but both have significant historical trauma (Bethnal Green disaster killed 173 people in 1943). The psychological weight of those events is powerful regardless of hauntings.
