I am looking for an 0-6-0 "Jinty" tank engine with a view to DCC conversion. I note there are several variants in LMS maroon livery that are DCC compatible. The older one has a Ringfield motor and the 2009 version is, I presume, made in China with a sealed motor. Would there be any difference from the point of view of the ease of conversion? Also which motor would be best, in DCC form ,for shunting?
