Three stories from More About Thomas the Tank Engine provided additional roles for Bertie the Bus, Terence the Tractor, and Harold the Helicopter.

In August 2020, there was a leak on Twitter that showed that the crew had filmed virtually the whole episode, including and up to the scene where Donald and Douglas swap tenders to impersonate each other (the scene that made Allcroft deem the story too confusing to air on TV), and the audio is the only thing missing.

Scripts for three Railway Series stories, Percy's Promise, Gordon Goes Foreign, and Double Header, were leaked the same month.

"Percy's Promise" and "Double Header" (renamed Time for Trouble) were later adapted in the third series.

Series 2 was first released as three separate VHS volumes by Pickwick's Screen Legends imprint in 1986.
