Dave, I don't remember going into any details about uncoupler locations. When I shot that video, I only had them on the stub sidings in the yard. So.... on storage yard tracks, I am installing them as close to the switch as I can and still have clearance to get around the last car on the siding. On the interchange tracks I am placing them like the yard tracks to maximize the # of cars I can drop at the interchange, so same scenario as close to the switches without causing fouling. Same situation again with my "run around" track and switch set-ups. I'll need to install at least in the run around, so I can drop a car(s), uncouple and then run around it and the get the engine on the other side to service facing point sidings.
On industrial sidings like the coal tipples I am placing the magnets, where I can take advantage of the "delayed coupling" feature with the Kadees. So even though I may want to spot empty cars under the coal tipple, the actual uncoupler is about 3 to 4 car lengths away from the coal chutes. If you're not familiar with "delayed" coupling, essentially you uncouple two Kadees over the magnet, leaving one coupler over the magnet, then back away an inch or two, and then reverse direction, and come back in slowly. The magnets will actually pull the shanks away from the centerline so that the knuckles don't line up and "couple". At that point, you can push the car down the siding and drop it a warehouse door, or coal chute, or any specific spot you want to leave it. Since the knuckles didn't lock and engage, you can spot a car anywhere down the siding, without having to have an uncoupler at every door on a warehouse. Yes, awkward to explain, but I don't want to shoot anymore video tonight. I think there may be videos on YouTube of Kadee Delayed uncoupling. This is a feature I look forward to using once I start actually operating the layout more.
Mark the station is coming along great.
