6,600 hp for one wagon - what a waste of resources! 66426 & 66430 pass Tredington on 3 June 2010 with the 6M67 14:02 Bridgwater to Crewe nuclear flask. I was sorely tempted not to bother taking this picture due to the severe backlighting and lack of interesting traction, but the sheer ridiculousness of it warranted a picture. All nuclear flask trains are double headed regardless of load, but this still seems a little over the top.
