Experiment for more interest in the grade, to break-up the many parallel lines. Not sure if I like it or not. Its all R27 (==O72) to reduce the added drag on a train climbing the grade with curves (except one R20 (==O54) near the top, the turnouts are R20).
I hope there is enough commercial interest that Lionel invests more in this track system. 1/4-section of S27 would be great in making graceful curves. And add a #4 command switch (LH&RH). And R24 (S48) curves would be great as well. And fix some of the production problems I am encountering.
