In 1991 a new freight flowed commenced in North Wales. The traffic was acetic acid from BP chemicals in Hull and the customer was Warwick Chemicals in Mostyn. At first the 4 wheel tank wagons that were used were conveyed by the Warrington - Llandudno Junction Speedlink service. They were then tripped to Mostyn using the Speedlink loco, invariably a Class 47. Following the closure of the Speedlink network, in 1992, a block train working was started which ran on 3 days per week. The traffic continued until the early part of 2002 when, due to a change in distribution arrangements, it went over to road transport. The only remaining traffic at Mostyn then were steel girders for export to Ireland and this finished in 2009.
