They appear to be compressed air locomotives of one sort or another.
Would be an interesting model if built.
Have a couple of pieces of different rolling stock people cannot figure out what they are.
The excavator is available in HO, cannot remember the name of company that has produced it though made in Europe.
Will take a look through my CM magazines, believe it was shown at the Nurnberg show this year.

As far as I know there are is plastic H0 static version that I think is by BUSH and a 3D printed version that can be ordered in any scale but not convincing for me.
There was also, a couple of years ago, a fellow offering a working, hand built brass one of which I can't recall the scale.
The last was clearly a lot of fine work but not convincing for me and neither for my girlfriend Mss. Impatience:
after ordering one and full payment in advance should wait a full year for delivery.
I am not sure about the price because never asked but I suspect anyway it would have been considered terrorism by Mr. Wallet.
A dozen of years ago I helped to rescue from an old factory an O&K one running on 700mm gauge that was really hijacked by the vegetation.
Sadly, I lost all photos of it.
Later -I think it was 2010- I had the pleasure of photographing another one at the Smalspoor museum in Valkenburg, here in the Netherlands:
I seem to recall seeing a film, not too long ago, showing a scale model,
fully operating -can't recall the scale- but ... hmm ... may be I was just daydreaming ...
Those are technologically simple machines but I am sure a row of headaches to model. I wouldn't dare to try.
I would be happy with a static model but it would take too much of the already non available place here!
Anyway the nicest ones - both, the European and American versions- are the old.
Actually I would be happy getting the mechanic components 3D printed for building a static version of these ones.
In a river scene with the dredger loading skips that are brought to the bank on track laid across a row of boats.
I have somewhere a prototype photo of that but no idea where.
