Monaghan is not regarded as a stand alone depot in BE, technically it has no allocation of its own. For years Thurles was considered a sub depot of Limerick and thus buses maintained in Thurles were 'allocated' to Limerick. Also its safe to remove OP 23 and DA 1 from the list as they are withdrawn. I will try and check the P and OP numbers left as I'm sure there are more withdrawn.
