 While the old MGWR main line was able to access the Dublin loop line to Amiens Street via the North Liffey line Newcomen Bridge junction this was not available to heavier engines such as the Woolwich Moguls due to weight restrictions over the lifting bridge over the Royal Canal.The alternative route via the Drumcondra link line would have required reversals to the Glasnevin and Drumcondra junctions so the connecting line also remodeled at the same time to allow direct through running.The associated complex was finally closed on 8 April 1961, having been used as the steam depot for Dublin between 1937 and this date.
