One of the main new feature is improved cooperation between pantographs and overhead line. Unfortunalely, this wasn't working before and not much care was put into the overhead lines to be in right place. So, on present sceneries it is very easy to break the pantograph in hunderts of places. The lines must be edited and I hope this will be done in next months. I've corrected the overhead lines in Quark scenery, what took me several days. This should be available soon.
Other main feature is integration with code created in 2007, which was not included in versions done in 2009 and later. It mainly concerns support for battery, some features of ET40, ET41, ET42 and many extra telltales.
If there's a need, I can translate the descriptions on rainsted.com, however I need some help, as my translation may be not always easy to understand. ;)
