As we started adding chokes everywhere it became easy to loose track of which piles of passenger cars have and have not had the choke inserted yet. This is not super easy to measure on the layout since the DCS packets are super short (few ms) and you need an oscilloscope to see whats going on. Also some passenger cars are complicated and have parallel connections soeven if you put a choke at one pickup, a low impedance path is still presented at the second.
Curious about the high-lighted comment. Are you saying the standard practice is to use 2 chokes? In other words, one per truck inserted in the wire running from the truck roller to a small hole in the car floor? This goes to the sub-conversation about the hassles of opening up the car to make the modification - and hence why not just do an LED surgery since the patient is already under anesthesia and opened up. The point being, when you say it's easy to lose track of which passenger cars have the choke inserted, why wouldn't you just look at the trucks to see if the 2 chokes have been inserted? Not trying to be a wise-guy but am curious; I do realize there are lots of guys who are loathe to open-the-patient to perform wiring/component surgery. Much easier if the solution can be performed without surgery.
