VERY atmospheric !! Inside may be dark and dirty but outside doesn't look very inviting either. Kinda makes you want to stay in the shed. I love the small reflections in the oily puddles near the camera too. It seems to me that the image is more about the conditions/weather than the loco itself. Another "REAR three quarter" shot , these are becoming a bit of a trademark - you've certainly nailed this type of shot.
Well Done,
Dougie.

Thanks very much Dougie. Much appreciated. You're right about the rear three quarter shot - my favourite angle.
Cheers
Pete
