The clever bit about the Bakerloo tunnel is that it allows trains that

terminating there, this becomes a less good plan.

Possibly-ignorant question: why can't some Bakerloo trains go beyond
Queen's Park? I looked on the interweb but couldn't find anything about
some trains being different to others.

Sorry, i phrased that badly. All Bakerloo trains are, as far as i'm aware,
capable of going beyond Queen's Park - it's just that some don't currently
have the opportunity to do it, because north of there, the track is also
used by suburban trains from Euston (QP being where the Bakerloo tunnels
and Euston surface tracks join up), so there isn't enough capacity (AIUI).

Continuing the tunnel from QP would have meant trains which currently
terminate at QP to let Euston trains go through could carry on somewhere
else instead. However, the current plan is for the suburban service to
Euston to be extinguished (or sort of replaced by surface trains that run
from the NLL via a link at Camden Town, but terminate at QP), with only
the Bakerloo using the track north of QP, so the tunnel would be pointless
in that respect.
