BASICS
> Traditional two-wire systems use some form of ‘cab control’, maybe only one, or several.
> The track is divided into sections, where two or more controllers (cabs) are to be used.
this allows for simultaneous control of locomotives, and also helps in any ‘trouble shooting’.
> A “one engine in steam” layout should not need separate sections.
> Isolation of locomotives can be achieved using the points alone.
> One rail is normally connected together for all sections (the common return), and only the feed to a section is controlled by switches.
GENERAL
> If using walk-around controllers (throttles) on larger layouts, put separate point controls close to their main place of action.
There is little to be gained from using a walk-around controller, if you have to keep returning to a central control panel to change a point.
> Use a positive connection to point blades/frogs via a switch - for electrically operated points, preferably on the point motor.
CONTROL PANEL
> Mimic track arrangement on the panel
Include significant ‘scenic’ markers
> Only use switches when needed (otherwise use points to isolate)
I.e. When there is a need to operate a loco in that section, with other locos operating in adjacent sections.
> For multiple ‘cabs’
Use change-over switches for two cabs (need to identify which is which)
Use push button switches for more than two cabs.
CONNECTIONS AND WIRING
> Use wiring with enough current carrying capability, particularly for long runs, and for remote point motors.
1.4A (7/02), 3A (16/02), except outside in garden.
> Use a colour-coding system as much as possible.
> Keep a record of colour coding and pin connections
Its a ‘pain’ until there’s a problem - then its brilliant!
> Keep wiring on baseboards tidy, and orderly, but leave a little slack at each end
Reduces the chance of damage and can aid in troubleshooting.
> ‘Manage’ all flying leads. Some options are:
Keep all leads as part of the control panel, so they are always in the right place at one end, and transported with a small package and therefore less prone to damage.
Use different connectors to prevent incorrect connections being made.
For leads attached to boards, there should be a ‘‘parking’ position to use during transit or stowage.
