I believe water could be picked up at speeds of up to 70mph. Above
that and there was a risk that the scoop would be damaged.
There was also a minimum speed, below which water would not flow
into the tender. Perhaps 20mph.
The film shows the fireman looking at a water gauge consisting of a
vertical pipe with holes in it. The fireman had to get the scoop up
quickly when the tender was nearly full. If he didn't then the water
would cascade out over a downwards pointing overflow on the rear of
the tender, washing over half the leading coach and sometimes
washing forwards into the cab together with coal. Think of the size
of the tender and how quickly it filled up to get some idea of the
volume of water flowing up the pipe from the scoop.
The fireman also had to get the scoop down at the start of the
troughs and up before the end of it (at slow speed the tender might
not be filled fully so the fireman was trying to get every drop).
Damage to scoop and troughs would not be appreciated, especially the
The arrangements to refill the troughs rapidly after a train had
passed were fairly impressive, with some big pipes.
Sometimes the dome which directed water from the pipe down into
tender would be blown off due to failed restraints. As well as
producing a spectacular fountain of water the dome, a fairly heavy
thing, would shortly be crashing down on the lineside.
In the worst freezing weather staff would be deployed to keep the
troughs clear of ice (the heating only worked fully down to a little
below freezing) and keep ice from splashes building up on the rails.
Lastly, the plan was to keep a few sets of water troughs (it might
only have been one set) for use with diesel locomotives. This was to
refill the train heating boiler. However, despite many experiments,
they couldn't make the scoops work reliably at much over 70mph. The
solution was to fit larger water tanks to the locomotives, removing
the scoops saved some space and I have a vague recollection they
reduced the fuel tanks a little.

They were mainline trains. The new A10 built near here has that
facility but can't use it because there are no water containers left
in the tracks. They had to increase the water capacity on the loco.
Limits its range
It used to cause a lot of "merriment" in the office when the driver
got back to the shed if he forgot to wind the scoop up before the end
of the trough.
My late uncle Jack was also subject to a degree of "merriment in the
office" after driving an ammunition train to Glasgow during WW2.

That's a good answer, a very good answer, but no.
He used to piss in the firebox. Next !
Clue # 1 : His train was standing on the Ribblehead viaduct.
