Update:
I have not done a lot this past week; it has been very busy at work, and last weekend I did a short citytrip. There has been some progress; the Pekeltram variant had it's snowplow installed (based on this image:
https://nl.m.wikipedia.org/wiki/Bestand ... 427%29.jpg).
If anyone would like to create repaints already... If you send me your creations I'll put a screenshot here, until ofcourse the tram is ready to be downloaded.
As this texture file suggests, the repaintable tram is the GTL8-II with original front. I have modelled all doors for this tram seperately, so the doors do not all have to be the same color; the doors can therefore be included in a continuous advertisement livery.
