The Peco ‘Shows You How’ series of booklets give practical, clearly laid out information and instruction on a wide range of model railway topics. This booklet is a companion to our booklet Wiring the Layout Part 1 (No 4), and takes the exploration of basic wiring techniques on to look at more advanced electrical projects such as Cab Control. See also booklet Wiring the Layout Part 3 (No 21) which explains the neccesary wiring for Electrofrog 3 Way Turnouts, Crossings and Single and Double Slips.
