This is also the final season with the original rendition of the Engine
Roll Call. Despite this, a few latest DVD releases which contained
Season 19 (with some Season 16 or 18) episodes retain these. When the
six episodes from Dinos and Discoveries aired on PBS Kids in May 2016, it used the Season 19 Engine Roll Call, opening and ending.

* Like the seventeenth season,

 although Arc Productions had officially taken over the animation
aspects of the television series, the episodes still used the opening
titles and closing credits made by Nitrogen Studios. This was the final season to use their opening and closing footage and from the nineteenth season, the opening and closing footage was made by Arc Productions.

* According to Ryan Hagan of SiF, the episodes in Spills and Thrills were going to be part of this season.
