Human excrement deposited onto train tracks when passengers flush the train toilet while the train is at the station.

A pile of moist toilet paper (resembling mashed potatoes) with a deposit of human excrement (resembling a sausage) protruding from this.
The pile of 'Bangers & Mash' on the tracks at Platform 8, Reading Station is a particularly striking specimen.

Bangers = small spicy sausages
Mash = Potatoes Mashed

The contents of a well-used but badly flushed lavatory, the bangers (sausages) being the turds and the mash (mashed potato) being the bog roll.
"Cinders and ashes, Thomas, your coaches are a disgrace", cried the Fat Controller. "There's soot all over the windows, used tickets all over the floor and Clarabel's khazi is full of bangers and mash!"
