Union Pacific FEF-3 4-8-4 Northern type steam locomotive, by Smokebox

[UP3985]

Ok, I did some digging and found out that the W BD Sep. system changes really aren't much visually, but it's the mechanical side of things that get weird.

A note about those pilot wheels again: The centers are indeed white. I agree! it looks much more masculine!
***BUT it does still look nice without them!

I'll fix that in a jiffy

I've changed the fireman's side to match the photo without chrome embellishments.

Just curious smokebox, are you planning on adding the ability to blow down the boiler? Ive seen steam locomotives do this and think it is entirely awesome!

This is indeed happiness!

You know you are driving us more crazy with anticipation with every screenshot?

That is the cold water turbopump and the stoker screw channel, right?

Yes, it's the Worthington pump. As for the stoker screw channel, no, the part sticking out at the back is the rear of the engine frame and below it is the housing for the two coupling bars that connect the loco to the tender. The rear of the frame isn't quite finished yet - there's a curved block (is it a bumper?) that has to be added.

There are so many pipes and tubes on this loco, many more than on the Consolidation, especially under the cab! I'll be glad when they're all done. I might just leave out some of the pipes - the ones that can't be seen unless you go up close and stick your head in there below the cab floor.

My guess it is indeed a bumper, you probably see a likewise contraption on the tender front. A double drawbar connects engine and tender?

As for the piping, obviously any that isn't visible unless you are a qualified steam loco pipe fitter is a waste of poly's.

Most important pipes and connections are the armoured/reinforced/corrugated or whatever it is called feedwater hoses from the tender to the live steam injector on the engineer's side and to the Worthington turbopump on the fireman's side. And the main fuel oil line, which is probably wrapped in insulation. I know flexible hoses are impossible to model, but fixed, rigid hoses should be there. As long are the loco doesn't go thru sharp S-curves, the rigid hoses won't swing out too far I think. Wether to connect them to the engine or tender is best determined with some experimentation. The cab end probably swings and sways more than the tender front, so afixing them to the tender would seem the most logical choice. But then they possibly don't mate up with the inlet parts?

Will follow your progress with interest and anticipation.

Here's a photo showing the double drawbar and all those pipes.

I have been wondering what to do about the flexible hoses. On the Consolidation, they disappear underneath the tender frame, so I had them attached to the loco, and when you go into a curve, they slide underneath the tender but it goes completely unnoticed. On the FEF-3, the pipes go into the side of the tender, so I'll have to do something else. One idea I'll experiment with is to split the pipe in the middle, with one half attached to the tender, the other to the loco. It would have to be split at exactly the right spot so that on a curve, the two ends that meet in the middle would appear to stay joined.

Can make the connections between part of the drawbar coupling between loco/tender so they visually can flex and remain connected

I see what you mean. It'll be tricky though, because the positioning has to be extremely precise.

attach it to the loco's rear boggie............ ?

I had thought of that too, since the trailing truck swivels, obviously, but again, the tricky thing is that both ends of the hoses have to be rigid, so they must be split into two parts. If I attach the hose to the trailing truck, or to the coupling, it'll probably cause both ends to move from where they're supposed to be connected.
