47206 passes Mostyn on 30 March 1991 with the 7D56 Ellesmere Port to Llandudno Junction (for Amlwch) chemical tanks. The grey tanks next to the barrier vehicles at either end of the train are ethylene dibromide empties, and the red banded white tanks contain chlorine, to be used in the process of extracting bromide from sea water. An interesting train, which ceased running a couple of years later. Unfortunately the weather on this occasion was not very good, with the grounded former Sealink 'Duke of Lancaster' ship in the background almost lost in the mist.
