Video of a CL145 firefighting tanker aircraft from Quebec demonstrating near Martha's Vineyard. The second half of the video shows a few scooping runs, all sorts about that process became clear when the water started pouring out of the side of the fuselage of the airplane.

Very cool. I've seen photos of a converted DC-10 dumping water in CA; I wonder whether they scoop on the fly.
Somewhat related: I believe that the NY Central used to rewater steam locomotives at full speed via troughs between the rails.

I thought I read somewhere that the DC-10 didn't. I don't know about the C-130s they use for tankers, though. That'd be something to see (however, out there on the back side of the Sierra where they seem to use 'em most, I don't know where they'd find a lake big enough to scoop out of).
Apparently in the U.S. they called the rewatering trough a track pan, I can't find video, but there's a picture Ann Arbor Model Railroad Club Kinnear Track Pans page and this forum page has a comment that says, among other things:
... I used to spend many hours at Bushy Troughs on the WCR, 12 miles north of London, Euston. I was just a few feet from the track and enjoyed the frequent passage of fast and slow, passenger and freight trans collecting water on the move. The scoop needed lowering and lifting with skill. The fireman would need to be quick turning a screwed actuator. At commencement of the troughs the scoop would be quickly lowered energetically by the fireman who would then watch the tender water level gauge to estimate when to start lifting the scoop. If the lift was late then there would be an overflow, washing coal off the tender and soaking unwarned passengers in leading coach compartments. ...
