Back then my three favourite places to catch the numerous freight diagrams were limerick junction, Cork kent and gouldings in Waterford.Then again north esk and abbey junction were good spots as well. Waterford was unbelievably busy - lots of liners,cement,fertilisers,grain,beet,guiness. Cork had guiness,cements,liners,ammonias,ferts. After a few hours at limerick junction you d have marked off a lot of loco numbers.
