Thanks for sharing. Do you know from what wreck footage this is from, aka is it from the debris field or stern section. Would love to see exactly where this is.

Beautiful footage, wish there was more of the engine room.
I think that those small plaques are to label the reversing engine control lever. So the engineer knows which way to push the lever.
It doesn't look like a telegraph which, alas, remains a mystery

I think that the plaque would say AHEAD and another ASTERN. I say it as the location is next to the reversing engine controls, one of the parts looks similar to the control lever, and the plaque has a slight curve, as if following the arc of the lever when moved.
Engine telegraphs typically would look the same as the ones on the bridge, sometimes mounted on a pillar with the handle at the bottom.

You're welcome Cam. It's a nice piece of detail to see, would never have known it was there otherwise.
I'd love to see the Engine order telegraphs and where they were mounted. Zero information I can find about them, trying to guess for a model I may make

sure thing,
skip to 6:26
Unfortunately we can't see what's going on here as they are too close - should have stood back a bit. I've seen a picture of the two reciprocating engines in the engineroom on the bottom, but wonder why the cameras spend years on the bow but never venture anywhere near the stern! Are there any videos of the two engines in the stern part, or the camera going between them?
I agree with the "Ahead/Astern" plates that they would be from the reversing engine. The telegraph cards were not marked with plates, just on the dials themselves (the usual DS, S, H, F). I cleaned one once and all the markings came off! Had to reinstate them with felt pens... I believe all three telegraphs (from a post on this site a few years ago - Stevefury's excellent 3D model I think - where their position was discussed. The consensus of opinion was that all three were on a post between the two main engines. There was of course no telegraph for the lp turbine, the 3rd one was the emergency telegraph, though how that was supposed to be operated I don't know.

Yup! I've been waiting for someone to ask so I can share these with y'all
Stern Exterior Mudline and Hull
Engine Room and Boat Deck
Plenty more here :)

Well, i seemed to see two propellers, so why can't we see the centre one seeing as how it's more or less on the same centreline?
I think I saw a telegraph quadrant when they speeded up the view, but they should have had a window showing where you actually were - were there two engines in the shot or just one of them several times? A shame they didn't "swim" between them to the after engineroom bulkhead

Hi Stephen,

From what I've read on other threads in this forum the belief is when the stern impacted the sea bed, the two wing shafts were bent upwards. The centre prop, being protected by the keel, stayed in position and is well buried down in the silt.
This sadly means the 3 or 4 blades on the centre prop argument can never be truly settled. Although most agree now it's likely 3 bladed

That is because they are not on the same centreline any more. The two outside props were bend up, the starboard one is on the high of F Deck and the port one about F/G-Deck.

maybe the center propeller is stronger, I agree with Sec.

Hi again Stephen,

What time was the quadrant you say you saw??
