The points you raise are certainly VERY VERY valid S.A.C The experienced part was pertaining to the modifications done to the model by some of the members on here. You yourself have been on here for 4 years and have shy of 4,000 posts. You have also taken the task of trying to rectify the VEP (which you shouldn't have had to in the first place) and in my opinion I would say you are an experienced modeler. I have only been modelling fora few months, I haven't even had practice at ballasting track yet let alone tackling issues with a VEP.
