Radio ga ga

Kenny Mackenzie, by e-mail

After inheriting a ‘O0’ gauge layout, I experienced difficulty maintaining reliable operation. This was because of the usual problems: loose connections, dirty track and engine wheels, and poorly fitted fishplates. All of these factors prevented enough power or electricity from reaching the motor, which drives the locomotive. It seemed to me that the answer was a locomotive that carried its own power supply, and that a battery was the best way of going about it. So I raided my old toybox and liberated a broken radio-controlled car. I removed the circuit board and wiring and installed it within the locomotive. I now have a radio-controlled locomotive that can run, despite the above problems.

Please note: Using electrical components that are not specifically tailored for model railway use can be dangerous. Always seek advice from a qualified electrician before attempting any project similar to the above. Below: Kenny has used four AAA rechargeable batteries to keep the locomotive running.
