I decided I would build a quick and relatively basic test track layout. Initially I did a single track double figure 8 with a single 13 deg crossing, four 90 deg crossings and 245 and 270 curves. (completed inner loops not shown) This seemed to work ok but after running for an evening and looking at Joes's layout, I decided that I could come up with something that was more interesting and could still fulfill the test loop function. So I rearranged, and did a pair of basic ovals that crossed each other. One would become more layout with turnouts and track added later. The other would remain just the oval. However now I'm experiencing issues with derailments/shorting entering the crossing. This is occurring with each of the AZL GP38-2's and the AZL SD40-2 I own. Looking closer I see the head of the rails on the crossings sits just slightly higher then the adjoining sections. Not sure what is the best course of action to take. Using a blank door for the base so I am confident all the sections at the same level. So I was wondering if anyone else has had issues with the Rokuhan crossings. As a side note the AZL SD40-2 loves the long straight aways, but it still loads down even on the 270mm curves. ~Paul E.
