Which Loco ????
 

Gentlemen

If I am off topic I apologise in advance, and if any one could point me in the correct direction I would be grateful.

Whilst at Didcot today - Friday 21st Sept. 2012 a freightliner 66 on 6M40 Westbury VQ to Stud farm pulling empty ballast boxes went round the west curve at Didcot and defied my attempts to identify it. Does anyone know the answer please or could point me in the direction where such knowledge might be obtained.

I thank you

Dave M
