Why don't you give up your connection box? Slotfire's main module has a complete power supply integrated in the board. That does look more attractive and saves storage room. Now there are only missing controllers and a transformator and you can get going!

With a Slotfire track you will never have to worry about feeding in extra power. The steel braid conducts superiorly. Besides the Slotfire system reduces radically the quantity of board crossings and points of power

losses. The contacts of the steel braids between two boards are so designed that an interruption of the energy current is impossible. On top of it the back and forward lanes are fed in simultaneously at the connection board.
