I'm putting a 4'x8' N Scale layout together. By design there is one mainline & lots of industries & yards with 14 turnouts [all electrically pwr'd]. I'm looking to your experience & knowledge in selecting the best coupler/uncoupler system for "N" cars & engines. I guess by best I mean the ability to couple & uncouple remotely with a high degree of certainty as some of the locations are not readily accessible. At this point I have 8 engines & 103 cars with assorted trucks & couplers installed. About half of the cars are M/T. I'm really willing to do what's needed to end up with the most reliable system available.
