Once Watson is reunited with Sherlock, the pair look at a strange video. It shows a suspicious man attempting to travel one stop on the District line from Westminster by using a Jubilee line train.

But the man has vanished by the time his Jubilee line train reaches St James's Park. Which isn't that surprising, since St James's Park is only on the District line

He's probably been diverted to Stanmore.

In reality, this was probably filmed on the disused Jubilee line platform at Charing Cross station.

And Sherlock concludes that the "five minute" journey between Westminster and St James's Park must have somehow been made to last ten minutes.

In reality it takes less than two minutes and at peak times there's 28 trains an hour running along the route, leaving little room for delays. But who are we to question Sherlock?
