I totally agree with you. But in my case, I do have to add that while I can see taking certain liberties with the prototype on a model railroad, I personally do not having to 'explain' things even to myself! if I stretch things to routinely include rare or unlikely events, cars, engines,ladings and/or trains, I am going to be asking myself if I really did choose the right railroad to model!
This is one of the many reasons that I value this group and it's members who share so much, so often.
