Just finished planting the non-scripted AJS Turntable in my engine yard. Approach track starts as a left divergence of of the yards main track, appropriately signaled at the junction. The end of the turntable approach has a red condition as indicated by a USA 04 signal. There is a stub off of turntable stop 0 with buffer installed. Track Marks are in place on turntable skirt as indicated in the tut. Either I have missed/forgotten something or the AI is not seeing across the turntable bridge. Can someone lend some help here. Thanks
