Now, warm-up question, what's that line called? I have a map calling the
tracks 'up airport' and 'down airport', so is it the 'Great Western
airport line'? That sounds absurd clunky. But if i just call it the
Heathrow line, people might think i mean a bit of the Picc. Anyway.

The branch itself is usually just called the Heathrow Airport spur or
similar.

I think the names "Up Airport" and "Down Airport" exist mainly to
differentiate them from th main/relief lines during the section where
the GWML has 6 tracks.

T5 to T123 won't mix well.
So, that line is two-track to Heathrow Central, where it singles down for
the bit to T4. This map i have also shows the extension to T5 as
single-track. Is that true?

AFIAK the route to T4 is double track throughout, but it has an
unusual platform crossover that essentially acts as a short single
track section. The route to T5 is also double track, though the
junction might be single lead.

Not to mention that AirTrack and a single-track stretch from

I assume since AirTrack has its own platforms at T5, it will terminate
there rather than running through to Central.
