Went here with Subbrit in 2009, fanks to all involved 
"Charing Cross used to serve as the southern terminus of the Jubilee line, but these platforms were concreted off when the line was extended towards Waterloo and then off towards East London in 1999. The rest of Charing Cross station remains open.
Looking at tube maps from 1974 and 1986, it becomes apparent that the stations at Strand and Trafalgar Square somehow managed to disappear between those years, only to be replaced by a single station at Charing Cross. Before any readers depart for the Charing Cross area to look for a disused station, it is important to note that Charing Cross was formed from these two stations when the Jubilee line opened between them. There is in fact no disused station at all, and the only hidden feature is that of the disused Jubilee line platforms mentioned above."
