9v PF 9 Volt 4

This is using Power Functions Pulse Width Modulated output to control Lego 9 Volt Trains on two Track Circuits with a 9 Volt Train controller.

 

You need two 9 Volt to PF converter cables to achive this.

 

Also you need a modded connector with Diodes.

 

With this you get better Train Control and a lot more pulling power due to the Pulse Width Modulated output from the PF IR Reciever as against the varriable voltage output of the 9 Volt Controller.
