If you have new graphic for trolley catenary, you can't have trams and trolleys. Anyway, it's GREAT Patch feature!

Hope some bugs will be fixed soon. So, I have some suggestions. Patch developers, please correct me if I'm wrong somewhere:
1. It'd be more realistic to dissalow trams to turn around (hope it's possible and not dificult).
2. Allow one more road slot (if one is added, it'd be no so much dificult to add one more). Then it will be:
road slot
tram slot
trolley slot
3. Add longer drive-through stations (is it possible?) and articulated RVs (it's very difficult, but somewhere I saw pic eis_os did it). Then will be possible trams with trailers, and so many useful features (for example, trailers for trucks etc.)
