I do wish they'd try turning round the Stratford-Crossharbour trains
there though.

I'm not sure there are any Stratford services which terminate at
Crossharbour any more. They either terminate at Canary Wharf or (in the
morning peak) run through to Lewisham.

But if there are any, the siding just south of Crossharbour is better
for reversal as it's nearer and it lies between the south- and
northbound tracks, whereas platform 3 at Mudchute involves crossing the
northbound track.
