That's the reason I'm making this wagon set, because I couldn't figure out the 2cc set's code very well. However I don't intend to rewrite the existing 2CC set, for the sake of backwards compatibility, and because the engines and MUs work quite well as they are. It is also very easy to add more trains and improve/tweak sprites. However the wagons were coded differently so I decided they would need a complete rewriting, and I decided to put this in a separate GRF so as not to bloat the codebase of the 2CC set even more, and to enable it to be used separately and with other sets.
Also, I have already added some freight wagons in my local development version, I'm implementing bits of code from the Dutch trainset and experimenting with refit variations and recolours to give lots of variety. (Not lately though, but after the exams I might find some time to continue work)
