Missing Murdoch is a short magazine story.
Whilst pulling a goods train down the main line, Murdoch meets James, who is fed up. He tricks Murdoch into taking his load as well, but this proves too much for the big engine, and he rolls into an overgrown siding. James is sorry and starts looking for Murdoch. He finds him in the old siding, but Murdoch does not mind; the siding is much more peaceful than the Main Line.
