At one of our previous run days our No2 Club Locomotive broke down

After a few weeks of work the locomotive has been repaired and is ready to run again on roseworthy’s rails!

It was discovered there were two issues with the locomotive.
The first being that the key for the pulley on the engine had fallen out, this was fixed by boring a new grub screw hole above the keyway and reattaching the pulley
The second issue was the trim potentiometer which had burnt out completely, this was bypassed allowing voltage from the main potentiometer to flow correctly

Below are photos of the repair process
