Is bustituting an entire line on weekdays just so they can run more

Not sure what element of that is the core of you question. Doing
engineering works ahead of time, or works on a main line needing an
adjacent branch line to be closed to facilitate it.

They're not closing the branch for engineering work. They're closing it
because they've stolen its weekday paths to strengthen services on the
main line.
