Frank the German Engine makes a comeback after remaking Part 11.
Jase, Zack and Zicky are introduced as being numbers 12, 13, and 14 on the North Western Railway. YouTube user Jonathan140 stated they could be for the Mid-Sodor Railway, but Eli confirmed they were part of the main Sodor railway as Lady, Bill and Ben didn't actually have these numbers and also since Lady doesn't actually work on the Sodor Railway.
This is the first New Engine video in Felix Cheng's series since Part 6 without the Repairs Theme. It is also the only video without Felix Cheng's extended Thomas theme.
