I am working on a route based on southern Indiana/Kentucky, US. It's mostly fictional as I like doing surveying and using DEM maps. My question is this, I have a spur to a coal mine joining a mainline not too far from a control point and I wish to make it a manual junction (indicated by the black arrow). What I am wondering is how in real life this might work because the ascending grade is close to 3% at this control point (indicated by the red arrow). This would mean a coal drag would have to proceed through the manual switch and then ascend that grade and then stop to allow the conductor to return the switch to normal, and then hold and wait for the conductor and then start again on a steep grade. Would it be better to make the coal mine spur join within the interlocking and make the spur switch a dispatch controlled switch? Are there any real world situations that are similar? How would you design this? Thanks!
