Duck is the only major North Western Railway engine who does not appear in Thomas' memory line up of engines. Many of Thomas' other friends do not appear here as well such as Annie, Clarabel, Bertie and all other characters. Rusty is the only narrow-gauge engine to appear in the line up of engines in Thomas' memory.
When Thomas is travelling on the Mainland map, many of England's landmarks are present, such as Blackpool Tower, York Minster, Skegness and Tower Bridge.
This is the first and only solo song so far to be sung by Thomas in the CGI series, since all the previous were sung with another engine(s) or coach.
