After rereading and seeing what some have said and about track laying and whats consider good and bad in route building, I'm struck to how much this this discussion bears similarly to the disagreements of some of the model RR clubs I no longer belong to had. As for prototype track, with just the PRR as a guide, there's many examples I still can't be-leave existed as laid. And when others model this track, were condemned for there efforts. In trainz there are what I find to be great routes, or layout that have what has been said here as unfinished or poorly done track work. Then don't run them.
If a stander is to be made, then lets start with what can be enjoyed to all that buy the simulator trainz. I have gone thought three PC, and a forth being made. And I have no expectation that I will be able to run the traffic I would like to see with out a considerable amount of more money with the top content that now available. In the pic's shown as issues with route builder, I have had the experience of spending hours on construction, only to go back to find these issues in my route, they were not done intentionally. And with some of the larger routs, would be a job in itself to find and fix. The same issues with trees, new content while looking more realist, make the frame rate unacceptably, and a job to change out to run the layout or session. So it falls to ones goal of what you wants to represent in trainz. Run what you like, and have consideration for the most part given freely for enjoyment.
I am contentedly impressed what can be done and has been done in trainz, these top line routs are of rare talent. But to hold all us to these standers is in my opinion is not except able. It's a hobby, not a job.
