So TfL is building new railway lines for the service ?

No, but as you mentioned, only a fraction of the old network exists
(or at least, is available to LO services), so it's not really
relevant to current and future service provision.

The greater part of the network still exists in use. Apart from the
diversion of the eastern end of the NLL and no services now running
via Primrose Hill, the two main sections are running the same core
services (apart from reduction in traffic) much the same as they have
for the last 80-odd years. It is hardly "a fraction".
