OK, I think we'll have to give up - here goes. The Deanery was, up to 1869, the residence of the Dean of Raphoe. Among its visitors would inevitably have been William Alexander, who was Bishop of Derry and Raphoe between 1867 and 1896 and whose wife was Cecil Frances Alexander, who wrote "Once in Royal David's City".
The loco, as you have worked out is "Earl of Oakfield", a Keef diesel which runs on the 15" gauge Difflin Lake Railway, which runs around the grounds of Oakfield Park, formerly the Deanery for Raphoe cathedral.
I really think you should set the next question.
And to finish, a few more photos of the railway taken in mid August.
