Largely wagonload.
With sugar beet, the pulp was going in the opposite direction to the beet, so a train of beet empties might have one or two laden "H" vans containing pulp going back to the farmers. On a laden beet train, the vans are returning empty. Vans containing pulp could also be in the consist of an ordinary goods train.
With lime, wagonload included in an ordinary goods train.
Coal was somewhat different - in the normal course of things, a wagon here or there in a goods train going to some coal merchant down the country from Belfast, Dublin or Cork. However, trains of all or mostly coal wagons left Deerpark and Wolfhill in the 1920s and 30s. And of course, the narrow gauge Arigna branch would have closed years before the rest of the C & L but for the Arigna Mines at Derreenavoggy, which produced coal trains on the C & L - the only bulk traffic the Irish narrow gauge ever had - until the end in March 1959.
