Being led onto the train at the beginning of the episode, Kenny Bilko (Wells) screams "extraordinary rendition." Extraordinary rendition is a term used to describe the kidnapping and extrajudicial transfer of a person from one state to another. It has historically (and controversially) been used by the United States against suspected terrorists, generally executed by the CIA. The controversy here is due to those prisoners being tortured in the states to which they were transferred. In at least one famous case a Canadian citizen transferring flights in New York on the way home was renditioned on the basis of mistaken identity. There is a parallel here, except that Bilko is being sent back to Canada from New York, and the extrajudicial nature is more of a formality in that they are basically skipping the step of using the extradition process. ISIS gets involved in another rendition, of Román Calzado, in El Contador. In both cases the prisoners are being sent to legal authorities. Suspected drug dealers have also been rumoured targets of rendition by US government agencies.
Cyril is reading Three-Ten to Yuma by Elmore Leonard during the first scene on the train.
Bilko is a member of The New Scotland Front, an alleged terrorist group, fighting for a "free and sovereign Nova Scotia". In the Trailer Park Boys the story takes place in Dartmouth, Nova Scotia, a suburb of Halifax . All 3 guest stars are from Nova Scotia.
Malory does not want Pam to board the train at all for fear that she may stow away, "just like on the blimp". This is a reference to the Season 1 episode "Skytanic ".
Cheryl turns out to own half of the railroad that the episode takes place on. (The other half would be owned by her brother).
Cheryl's pet ocelot Babou makes another appearance in this episode.
Having mistaken them for terrorists in disguise, Archer tries to make the mounties put down their weapons, holding them at gunpoint. One of the mountees says "Maintain the right boys," indicating that they are not going to do so. "Maintain the Right" is the common English translation of the RCMP motto, "Maintiens le droit." It is also sometimes rendered "Defend the Law." In other words it is a reference to their role in maintaining order and rightness. "Maintain the Right" was also the title of a book of the history of the RCMP by Ronald Atkin and a 1940 film of the same subject matter.
Archer references the film "Hud," quickly pointing out to Lana that he hates Patricia Neal. Her character, a main love interest in the film, was originally black in the book, but for the film she was changed to a white woman.
