Tomix C11 DCC decoder

[GeorgeHInch]

My order with the Oigawa Railway C11 Thomas the Tank Engine from Tomix has finally arrived! It's in my queue to add a decoder into this model. I know Tomix is generally harder to add decoders to than Kato but since this was a special model I clearly didn't have much of a choice.

 

Has anyone installed a decoder in a Tomix C11? Any breakdown pics also appreciated!
