This shows the latest modifications done over the last couple of days. Notice the new speed controller, which I made some time ago. It does not use any type of resistor, it uses Diodes instead! Mine are 3 Amp rated. Each diode drops the voltage by 0.5 of a volt, if I remember rightly. It also uses a 1 pole 12 way switch, available at Model Railway Exhibitions. I like the action!
