Looks very good to me I like the Air Pumps. I lived at Consett and the line was at the end of our street next to the station bridge I thought the Loco numbers were 9206X. I don't recall 62099 I may be wrong.
There were three sets of Iron Ore cars 10 in each set but 9 ran in the rake one from each rake was held as a spare.
I had the fun of having a cab ride from the station to the gantry and the driver dropped me off at the station on the way back.
I was only 10 at the time. I remember having to keep my head down as we passed "Mr Willson" in Carr House West Signal Box.
