Hi every one i hope someome out there can help with my question, which is, i'm currently running an indoor twin track oval layout in dcc but have just moved house and now have the opportunity to extend it outdoors. what i would like to do is have a single spur coming off one of the twin tracks which then heads outdoors round a loop then back in, ie imagine a lollipop type of shape lol. so here's the question how do a wire it up without shorting out keep it simple please my knowledge of electrics is limited, thanks Bob
