The section of the Widened Lines east of Farringdon closed in 2009:
arrangements for longer trains on the Thameslink route to Blackfriars
meant that the platforms at Farringdon had to be extended at the east
end (because of the slope at the west end), thus blocking off the
junction. This section is currently being used for Crossrail work, but
once this finishes it will be reconnected to the Underground tracks via
a double junction at the east end of Farringdon. The line will run as
double track to Moorgate and will not be for passenger service, only for
stabling trains and emergency reversing. Originally the plan was for it
to be singled through platform 3 at Barbican and in platform 5 at
Moorgate (with no track at platforms 4 and 6 respectively). Each track
would have held five trains: two between Farringdon and Barbican and
three between Barbican and Moorgate. This has been replaced by a plan
with scissors crossovers at the centre of Barbican station and a short
distance outside Moorgate. Each track will now only hold four trains,
all accessible from the platforms: one each side of the Barbican
scissors and two at Moorgate. In an emergency a fifth can be stabled at
the tunnel mouth at Farringdon.

I wonder why LU needs sidings capable of holding as many as eight
trains? I can see why some sidings are worthwhile, but why so many?

I wonder why you're wrong about almost everything. I guess we'll never know.
