Almost certainly these were all scratch built by the owners/drivers. That's what model engineers do! However if you are keen to get into miniature railways and do not have the necessary workshop facilities or skills and patience (most of this scale of model take years rather than months to build) there are always second-hand fully built ones available (have a look at www.stationroadsteam.com/) or kits (take a look at www.pollymodelengineering.co.uk/sections/polly-locomotive-kits/index.asp).
