I rode on the 12:22 Virgin train from Bangor to Holyhead (07:20 ex-Euston) and returned on the same train on the 23 February 2002. I was surprised to see two locomotives one this train.

47757 leads 47789 into Bangor

47757 runs round at Holyhead

47757 couples up, the other 47 is ready to run round

The pair await departure of the 13:35 to Crewe
