The Mummy Train

Mark Twain used to joke that the wrappings for mummies were used in pulp for newspapers and their bodies burned to run trains.
But neither was true.
Instead, mummies were employed by the newspapers in the printing presses, shambling around the massive rollers.
If one got caught up in the machinery and torn to bits, who cared, right? They were already dead, their families long gone.
Letting them don engineer caps and run trains, well, that was a lot more dangerous. Mummy brakemen tended to ignore warning signals, and only so many accidents were tolerated before they all were retired.
