I decided to make a few tweaks to the front end as after studying some more photos I felt like the bottom half of the nose was too short. And it was missing that distinctive inward curve on the bottom lip. The three images show the model as it was, as it is now, and a reference photo. It'll never be exactly right I guess, but it feels a lot closer now.
I've also gone ahead and correct the height of the train and the coupler block to fit Dutch standards. I noticed the doors were quite low as compared to Oppies Dutch platform set, and so I wanted to correct for that. This means I have to make slight modifications to the bogies and pantographs as well to make it all fit between the tracks and the overhead wires in-game. The floor height is now 80cm above track, and the coupler sits centered at 1m above track. This makes it compatible with real world Dutch standards, and thus with other mods assuming they use the same standards.
