Both my triang hymeks run better than the ringfield version, one runs with the hornby decoder, the other is on a bachmann. I did however upgrade the magnets to the newer neo type, so the current taken is below 250 mA. I am just in the process of painting a replacement body for one of them, the original body was damaged some time ago. I managed to get a couple from Barry Marsh (ex modelspares) recently via ebay.

PS Jake, It was me who sent you the diagram.
