Are there features of railroads at key summit locations that show up repeatedly? How often do such locations feature a passing siding? Turning wye left over from steam? Set out tracks? Lap siding? Turntable? Industry(ies)? Do any simply have a peak in the single track where? Does it matter if the summit required helpers or not? I would tend to think so, as the railroad would put in some level of infrastructure for their operations.

Thinking at the keyboard about what I want at the summit of my climb for a N scale mountain railroad featuring helper ops.

I did something this week I haven't done in many years: I decaled a locomotive.  This is another one of my loco projects that's languished in a box, then on a shelf, waiting for me to spend some time on them again.  It's not done yet, as Dullcote and weathering are still to come, along with some wheel slip indicator details and window glass, but it's close.  About time as I painted it no later than about 1997.

I recently read somewhere about putting rerailers at both ends of hidden staging yard tracks. I really like that idea from a reliability standpoint, but my staging tracks are already installed, and would prefer not ripping them up to add rerailers if I don't need to. So here's the question - has anyone ever made ther own rerailers to add to track that's already installed? I'm using atlas code 83 flex track and am wondering if rails can be added, maybe similar to guard rails on a bridge section? Would that have the same effect as a purchased rerailer or not?
