One lingering challenge in the design of the LK&O is how to introduce elements (locomotives and rolling stock) from a wholly different time period into the scene in a manner that minimizes the negative visual impact. The situation is created as a result of conflicting interests. I want to model the AC&Y and I really like the looks of modern 6 axle locomotives. The newest locomotive the AC&Y purchased was a Fairbanks Morse H20-44 in 1967. This is hardly a late model locomotive. Take a look at the illustration of The Spirit of Cumberland coupled to AC&Y #508. Quite a difference, hey? Of course this is just a comparison, the two locomotives will never appear on the LK&O coupled together like this.
I have yet to formulate a good solution to this challenge but I am not going to throw in the towel just yet. It is still early in the design phase. Ultimately everything revolves around the track plan. Designing a track plan that can permit the 6 axle power to pass through the scene in a non-intrusive way is an overarching consideration at this time. If I cannot come up with a suitable solution by the time the track plan becomes final then I will admit defeat by locking down the motive power & rolling stock selection to the 1960-1975 era. If that becomes the case then the Spirit of Cumberland and other 6 axle brutes may have to make cameo appearances as if sent from the future through the rip in time space!
