In September 2003 the lines west of Crewe, through Chester to Holyhead, Llandudno and Blaenau Ffestiniog previously operated by First North Western trains were transferred to Wales and Borders.
The company will only run most trains in Wales and the Borders for about three months before the franchise is due to end.
In July 2003 the Strategic Rail Authority announced that from 7 December 2003 the franchise would be awarded for a 15 year period (subject to satisfactory reviews after 5 and 10 years) to Arriva.
