Frank and Eddie are a pair of twin railway barges (also known as car floats) who work with Top Hat, the railway tug, and are used for the transportation of railway rolling stock across the port. They are very quick-witted and are among the few that can deal with Top Hat's self-proclaimed superiority. Both of the twins speak with Cockney accents.
