Works number was 834.
The only L&LS engine delivered that had neither a leading nor or a trailing truck, Inishowen soon had its leading axle uncoupled to reduce the rigid wheelbase. Making it not quite a 2-4-0T because the wheels were all the same diameter
The little tank ran for 55 years until its scrapping in 1940.
