Having completed fitting all the droppers on the current scenic boards - roundhouse excluded - I have made a start on adding the BUS bars to the layout. I have decided to split the scenic section of the layout into a number of power districts or Zones as follows;
Zone 1 - Up Main
Zone 2 - Down Main
Zone 3 - Turnouts Group 1
Zone 4 - Turnouts Group 2
Zone 5 - Loco Shed Sidings
Zone 6 - Loco Shed coal/ash area
Zone 7 - Loco Shed rear sidings
Zone 8 - Loco Shed Turntable & Roundhouse sidings.
I decided to tackle Zone 5 first it being the easiest area to get at. Here are a few photos of work so far. I have added a BUS bar for the five loco shed sidings attaching wires from each dropper to the appropriate cable.
Part of Zone 5 includes the 5 shed sidings alongside the roundhouse and workshop
