66543 gives a helping hand to failed classmate 66564 with the 4O51 10:00 Wentloog to Southampton freightliner on 27 April 2010. Running over five hours late the pair are pictured climbing out of the Severn Tunnel towards Pilning. It shows just how vulnerable Freightliner's operation at Wentloog is, when the location is so far away from any rescue loco in the event of a failure.
