now that's a nice ME (or two of them), but not perfect. The logo is not mirrored on the other side, so both sides looks identically. That goes for both liveries. Also the taillights, there are only two of them, not 3. I don't know what the red pixel on the roof is for, but the real engines do not have red lights there, only white.
I found a few mistakes on
http://www.ooas.dk/ttdxd/trains/
1: Benzin is called petrol in English
2: the 3 bogie Triangel is diesel-electric, not petrol-mechanic. It's actually the same engine as MO, except there are just one of them.
3: t's spelled axle, not axel
4: it's spelled bogie, not boogi
Otherwise really nice work. Where did you get the pictures from? I mean the factory pictures of the steam locomotives, not the ones I linked to
Another thing. I searched the net for a photo of the rear end of the 2 axle Triangel motorcar. I didn't find any, so I made one myself yesterday when I was at the right location anyway. The engine in question is the same as the front shot. Because I showed up so late, I used nightvision and killed all the colours, but the metal is black and the woodwork and roof got the same colours as on the front. Notice that it actually got a white light on the roof in the rear. I presume it's only used for switching as it's a multiheaded engine and was meant to have one engine in each end of the train.
