facepalm.

You're quite right, of course, but I suppose they don't regard the
additional Heathrow station as an extension.

It's approx 2km, so rather more than just a new station.

Topographically it's almost identical to the Battersea Branch (~3.5km)
but maybe the writer thought it was like T4?

T4 involved 6.1km of new single-track tunnel.


Those almost straight new tunnels are among the loudest on the whole LU
network. It's almost painful. Does anyone know why?

If you mean the T5 tunnel, I imagine they're the only part of the tube
constructed with NATM.
