This friday afternoon in North Wall

[MOGUL]

Finding myself with a free hour in the fairview area on friday I decided to take a walk down to NW to kill some time. My expectations of any trains being present were low given I was half an hour early for the arrival of the IWT. However my fears were swept away when I got to the bridge on East road. 077 was idling just under the bridge with the laden taras awaiting access to the tramway and just after I arrived 230 arrived with a fully laden IWT from Ballina. What really surprised me was the presence of 219 with a fully laden container train sitting in the sidings near the stone bank. As the hour was horrendously late(13.20) for it to be Ballina bound I was wondering if anyone could elaborate on its presence?? Was friday's IWT held due to the RPSI railtour departing Connolly at its normal departure time or simply delayed due to a failure??
