Having been busy building an 8ft x 4ft layout containing 2 parallel running main lines and a goods yard of several sidings, temporarly laid out runs no probs with normal dc track clip as only wiring. I am going dcc. Will it work the same way or is it essential to bus wire it, or just advantageous to do so. Or not really necessary on this size layout. I do intend to floor out the loft later to build something about 16ft x 8ft which is the approx. space I'll have maybe more. Fancy doing Tyne yard and surrounding area as I worked from there as a railwayman for many years.
