I find this hobby very interesting because the amount of time one can spend on making every little detail they can possibly incorporate into their beautiful layouts. However, when it comes to locomotives, this becomes somewhat problematic. Most manufacturers do produce some really awesome locomotives with attention to detail being foremost on their minds.
As an example. Everyone knows MTH is renowned for their smoking units on their diesel locomotives. I recently purchased a brand new SD70Ace premier locomotive done up in the Penn Central livery heritage unit. This locomotive looks more like a steamer when she comes around the curve versus a modern green diesel. Obviously, this can be controlled by the DCS system, but it is so much fun letting her smoke up the room a little. The point? Well, this is not prototypical what's so ever of a modern green locomotive. Thus it looks out of place on a layout. Of course this is but one such example out of thousands that could be mentioned up in here. I just find it interesting that some do not care about being prototypical and prefer to sort of let loose when it comes to how they operate their railroad layouts.
I like realism allot because it adds so much dimension to the layout, but I am hardly predisposed to the idea that one must operate their railroad as perfect as can be and with absolute realism.
What are your opinions and thanks.
