Duck, Flying Scotsman, and Winston are the only standard gauge engines presently in the show who do 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 song to be sung only by Thomas in the CGI series, since all the previous were sung with another engine(s) or coach.
If one looks closely, they can notice that Porter is on the same track as Rusty, even though Rusty is narrow gauge and Porter is standard gauge.
Rusty appears on standard gauge track in the song despite him being a narrow gauge engine.
