Rather unusually for an Irish railway, it was more of a passenger than a freight line, and snappy running was pretty key to the operation. The double track section - which testifies to the traffic density either envisaged or achieved - was AFAIK unique in Irish NG (there were a few sections of parallel single lines eg at Ballinamore). The CBP locos which ended up in Leitrim gave a good account of themselves and lasted to the end in 59, although that long wheelbase barred them from the Drumshanbo line. Elegant locos in their way, although the NCC tanks in full maroon livery take some beating.
