Grandma - What big teeth you have got! More seriously, lovely composition, bang on focus but a wee bit tightly cropped?

Clever idea.

If only it were NOT so true!

Just timed it right, before their motion becomes noticeable. Very dramatic.

Works very well at several different levels

Black, smelly and gloopy! Happy New Year David

Nice composition. They used to thunder up and down the Great Central too at very high speeds on coal trains known as 'windcutters' until the inspectors put a stop to it (the trains were loose coupled, unbraked and the engines only have plain bearings!). The crews called them 'spaceships' due to the modern design and huge footplate area.

What a shame there is no bokeh competition!

Leaving the technical excellence aside, I liked the subtle colour shifts in the original - like the metallic glints off the pencil point. This one discards those distractions and concentrates solely on its sheer excellence.

That is some serious looking mud! Nice picture.
