It had been going well for the layout manager – until today when the sparkies cornered him and forced him to make some decisions.

The black button tops were quickly dispensed with and replaced by green ones and from a line-up of six, Dave chose the power knob.

If you press a blue button, you will change a point and if you press a green one you will power on/off a section of track

Simples!

PS: no layout managers were hurt / injured as a result of this posting.
