When I regularly travelled on that route, the problem used to mainly
be dwell times at Blackfriars, and access to London Bridge, which I
believe is just 2 tracks (1 up, 1 down) at one point. 15 minutes
between the 2 stations was not uncommon. Someone at Thameslink told me
an additional problem was that Southern trains 'had priority over
Thameslink trains at London Bridge' as it was 'their station', which I
was a bit dubious about.

Probably a load of rubbish as you say. London Bridge is a Network Rail
station, you'd have thought that would be known even by Thameslink staff...
