Having found out from Shaun Courtnage's excellent Class 47 List about Freightliner locos 47197, 47829 and 47805 working Virgin trains from Holyhead on 4 July 2004.

11:47 -
On Sunday 4th July 2004 I photographed the 1T87 11:20 Holyhead - Chester entering
Bangor with no-heat 47197 on the front ...

11:51 - 47197 makes an smoky departure

11:52 -
47829 tailing on the rear for return working from Chester

09:46 - On Monday 5th July I took the chance of a ride. I was surprised that the
locomotives were turned round, so Police 47829 arrives at Bangor with
1A49 09:20 from Holyhead

10:37 -
I got off this train at Prestatyn

I went over to the footbridge to watch 47197 departing to the distance

13:17 -
I caught the 1D87 11:38 to Holyhead (08:35 from London) behind 47805
seen running round at its destination 20 minutes late. The turnaround was very
quick for a 13:23 departure

14:00 - I got off this train at Bangor. These fine trains will be replaced by new units
in September. Yuk!
