Having worked the penultimate leg of "The Cathedrals Explorer" the day before, "Black 5s" 45407 and 44871 are now working back from Southall depot as 5Z73, 08:40 to Kidderminster Severn Valley Railway. With just the two support coaches in tow the engines have made light work of Saunderton Bank and have just shut off for the drop down into Princes Risborough, running several minutes early. The sun was at least trying again, but didn't quite make it! 10:29, Saturday 14th May 2011. Digital Image No. GMPI9011.
