I can't wait to see a video of the finished thing!
Well, at the moment I think we'll do without any drain and just apply oil to the gears before a run.
I can't wait to get it running too. Just need the on-board fuel tank and a new exhaust system. I could fill the gear case with excess castor oil from the exhaust system that doesn't go into the first gearbox, then it could finally overflow on to the track.

Thank you! I'm just a click on the keyboard away.
Here's the footplate, all one piece, lots of sawing and filing.
It weighs in at 3.4 Kg (7 lb 7 oz) now

Slow progress recently. Ended up cutting out the cab pieces by hand after wasting time and money on a scroll saw. Then spent a week waiting for a metre of 1/8" brass half round beading to arrive; to edge the window openings and doorways. The metre length wasn't quite enough, but the front and both sides are done. I've got some more on order for the rear sheet. It's quite an enjoyable process soft-soldering the beading. The most important part is annealing it first, otherwise it is far too stiff.
I need to have the superstructure finalised so that I can progress the exhaust, fuel tank, and controls.

Here we are, I've bent up the bonnet in the wood vice. I like the end-on view, it's got that menacing look of the truck in "Duel" (I could put some battered old engine nameplates along the buffer beam of victims, lol).

I have watched this thread from beginning to present and up 'till now have nothing to contribute to the project..... but I must say I am in awe of your engineering skills, combined with the infinite amount of patience you have shown in developing this loco.
Even your workshop is neat and tidy..... I must lie down now!.
Here's the latest progress, the side rods fitted, a test run on the line - pushed by hand...
The motion is a bit tight, it needs a good run under power.

Finally, I got the loco running again. Last weekend I had lots of fun soldering up a small on-board fuel tank from a can. It only holds about 40 mL, but it lasts for 20 minutes and can be topped-up when running.
Just keep filling until fuel comes out the overflow.
Video of the run

Recently I've been concentrating on the exhaust system. A manifold to turn the exhaust through 98 deg. Then a huge box for the gasses to expand in, and then exhaust pipe going up the front middle of the cab in between the windows. The exhaust box is all soft soldered together, and coated all over the inside surface with solder to protect the mild steel. The exhaust box has a capacity of about 200mL.
There's the oil drain at the base of the exhaust box.
