It looks like the steam valves are eccentric operated with the trip mechanism and dashpots, and the exhaust valves are cam operated without a trip mechanism or dashpot.
I've worked on this engine, as a volunteer for TWT. The four rods on the crossheads DO drive waterpumps. The empty crank drove 2 submerged well pumps via a bellcrank setup and these had sufficient lift to pull water up to the softening plant, 50 feet above the engine. The three larger pumps under the engine then pumped water from the softening plant to the reservoir on an adjacent hill, 120 feet higher than the engine, and three quarters of a mile away, 3,500,000 gallons a day, 24 hours a day.
@GR8TM4N Kew bridge steam museum also have a triple engine, Kempton just a few miles from Kew have the Greatest triple, go listen to that run as its more to size than this one.
Indeed, a very impressive engine. I did not recognize the valvegear. Mind telling me what valvegear it uses? Did not look like iether Stephenson link or Joy gear.
incredible, i'm glad i found this. nearby we have the Ryhope pumping engines in Sunderland.

I believe that Titanic had the same kind of engines. Very Interesting to hear how Titanic's engines sounded

That is a very unique crosshead construction with the (4) vertical rods.
Don't think I have ever seen that on a big engine.

is it possible that the waterpump piston is connected to those rods ( in the basement)

Ah, interesting, thanks. Just that I've never seen it before. Oo' Very interesting mechanism to watch tho.
BTW, I love the sound of that engine and the steam puffs from the stuffing boxes.

The valve gear is of a type that was devised by an American, George Henry Corliss in the 1840's. Hathorn Davey used "Craig's trip gear".

Very impressive video, with a good view of the engine and its parts. I hope we shall be able to see more videos from you.
