N scale couplers and switching

I have recently started building a layout following five years of armchair modelling. I have a collection of various makes of locomotives nearly all fitted with Microtrains couplers and most of my freight cars are similarly fitted. I have recently bought some Kato and Atlas locos and cars with their new type couplings.

I have started with a small freight yard and a passenger terminus and I want to use magnetic uncoupling devices. In the freight yard I have discovered problems using the Microtrains magnets that fit between the rails even when positionned using the MT height setting jig. I find that I get undemanded uncoupling or failure to stop in the uncoupled pushing position. I am unsure if it is because the Kato and Atlas couplers are incompatable with the MT magnets. Is hands off switching really a reality in N scale? Has anyone written an article about this, I cannot find any reference to N scale switching within Model Railroader in the last ten years that has mention of couplers and magnets. I am building a yard similar to David Popp’s Waterbury yard but it looks as though he uses a magnetic stick or wand of some sort to uncouple in the video. The Microtrains web site isn’t much help and I am unsure how many types of uncoupling devices they now make. Are there any electromagnetic versions avalable in N scale. Any information would be greatly appreciated.

Heres a great video on N Scale couplers…

Here’s one solution if you use C80.

MT part number Micro-trains N 98800173 (1311) .

most of my cars have micro trains couplers and trucks. most of my locos have accumates. i pulled out all my magnets in favor of uncoupling with a barbeque skewer or a rix pic. the problem is that the accumates don’t uncouple well with this method. the cars derail or the knuckle jams open on the accumate equiped car or loco. also it takes more speed to couple and sometimes i can push a car quite a distance without the accumates coupling at all. on another posting there is a consensus that kaydee’s are the only ho coupler that should be used. well in n scale micro trains couplers are the only one’s that should be used.
