 I just bought a PW F3 AA NYC set. The front coupler on the dummy keeps blowing open.It appears that it is some kind of electro coupler with some kind of actuating mechanism on the bottom of the truck. What can I do about this problem? I have Fastrak. Thanks in advance for any help on this. Nick

  A shoe? Plastic with a channel and rivet/contact? That would indeed be for an electro coupler. They tend to pick up power in some turnouts and open unexpectedly. Cut the wire, tie the shoe raised, glue it raised, paint the contact, etc. There have been a lot of threads on that fairly recently.

   You could open the electro couplers with a command board (part hasn't changed much), whistle relay (+ an extra relay), or magnetic reed switch if you wanted too.
