In relation to the similarities in the real and "fake" England in the play- another feature that has evidently been altered regards transport. As this play is set in 1832, and steam trains were invented between 1771-1833 despite the accuracy of this, it comes to my attention the steam trains of this time would definitely be too heavy for wolves to knock over off the tracks which the book states. We can only speculate that the author has done this to intensify the negative connotations of the wolves being more malicious, more corrupt and stronger than reality. This could further mirror the traits of the villainous characters (Slighcarp, Brisket and Grimshaw) who also seem to accomplish more than social fact would probably allow.
