An urban legend tells that in the mid-70s a bus on line 166 that covered the outskirts of London one day suffered the wrath of a suicidal madman. In his act he blocked the doors and made it burn from within. Nobody can go out, nobody can tell, that's why there are those who say that he can still be seen making his way in the cold London nights, accompanied by a chorus of screams of pain and hands that scratch the glass trying to escape.
