Okay: Since i dont know , where can i get those "itty bitty" Phillips screws preferably in a bulk pack to mount the couplers?? Also is there such a thing as a switch de-coupler piece ect, so if i want to park cars on a siding i can disconect themfrom the power circuit till i decide to use them?![Huh? ???](https://www.bachmanntrains.com/home-usa/board/Smileys/default/huh.gif)
