Great job, Nelson (as always!)
I am not sure whether this loco, in this livery had red connecting rods, though this became a UTA standard with their lined black livery, I'd need to check. But a superb job nonetheless!
That's BCDR green. The green carried by 30 in Cultra is co9mpletely wrong - it should look this colour. I think the lining was cream or pale yellow. It's still in BCDR livery, but has a new UTA plate. It nis possible, or even loikely, that the UTA's experimental dark shade was something broadlky similar to this, though the picture here shows it looking more "olivey" than it was.
