I just viewed a couple of video here on youtube about what Controllers are not NMRA Certificated. May want to check in to that.
One of the Hornby controller is not NMRA Certificated. It will run the Hornby DDC but not other manufactures Locomotives.

I don't know if this has been asked before, But I would like to know if you can equip any non-dcc Engine to be DDC ready.
Thanks in Advance. 

Dis-re-guard I found the info I needed.
