Victorian slang for a policeman — recorded in 1909 as police slang, dated there to 1883.
What it really means
A mutton shunter is a policeman. That much is certain, because J. Redding Ware wrote it down in 1909 with unusual precision: the entry reads Mutton shunter (Policemen, 1883). Policeman.
The label in brackets is the interesting part. Ware tagged every word with who used it, and this one he gives to the police themselves. It is not an insult thrown at constables by the street. It is, on his evidence, what they called each other.
The second half is easy. Shunting is railway language — moving a carriage out of the way onto another line — and it had spread into ordinary speech by then. A constable spends a good part of the day moving people along. Shunter fits.
The first half is not easy, and it is worth saying so plainly: nobody knows why mutton. Ware does not explain it. You will find confident explanations online; none of them come with a source, and the one source there is stays silent.
That is a better ending than a made-up one. The word survived; the joke inside it did not.
Where it comes from
Ware gives the word and its date but no explanation of the mutton. Stories that explain it are guesses.
Myths & misconceptions
We know why a policeman was a mutton shunter.
We do not. Ware records the word, dates it to 1883 and labels it as used by policemen — and gives no reason for the mutton. Shunting is a railway term for moving something out of the way, which fits a constable moving people along. The mutton is unexplained.
