I have a n scale 9' x 10' layout wired for DC with 9 different blocks. I have 2 powerpacks, and there are toggle switches for each block. 99% of the time I run layout by myself. I sold most of my engines, except for an Atlas MP-15 without decoder. I ordered 2 more for July, and now I am thinking about DCC. Questions: Should I replace the insulated railjoiners with regular ones, and leave one section as a "Program track"? I have 1 reverse loop, is this a nighmare for DCC? Should I replace all the blocks with 2 feeder wires? I want an all atlas system, is there a wireless controller, or can I unplug and plug it into other side of layout with a memory feature? can this all be done under $300.?
