153385 at work in its new role as Network Rail's Video Inspection Unit. This was a definite bonus, as the 2Q11 04:13 Eastleigh Arlington to Derby RTC (via Salisbury) should have been long gone by the time I got to this spot at Kennington, but as it actually left Eastleigh at 06:23, it was running 169 minutes late. Consequently it passed by just after I had arrived at the footbridge!
