Hi, I have just got into OO gauge modelling I have been busy building my layout, which is not set in a era as such, but will have diesel engines. I'm not really interested in steam engines. I would like to run diesels that were not saved for whatever reason, as I am interested in lost railways and trains. I have already got Dapol's Class 22 model, as none of these engines were saved. I would like to add to my collection more lost diesel engines. Is there a list of which diesel engines are no longer around and were not preserved? Thanks.
