Trivia

 * The last seven episodes of the season: Buckled Tracks and Bumpy Trucks, Mucking About, Cautious Connor, All in Vain, Tit for Tat, Mike's Whistle, and Useful Railway, were incomplete at the time Arc Productions went bankrupt and were finished off by Jam Filled Toronto after Jam Filled Entertainment bought the aforementioned studio.
 * Tracy-Ann Oberman joins the voice cast.
 * Only seven episodes were licenced to PBS (Sidney Sings, Diesel and the Ducklings, Saving Time, Letters to Santa, Love Me Tender, The Railcar and the Coaches, and Mucking About). However, The Christmas Coffeepot aired on Nickelodeon along with Terence Breaks the Ice from the following season. Other episodes from the season were eventually aired there following its official move in March 2018.
 * This is the first season of multiple things:
 * The first season of the CGI Series not to have any returning characters in CGI.

 * This is the second season of two things:
 * The second season not to have Thomas' name titled in any of the episodes, with the first being the fifteenth season.
 * The second season to have 28 episodes, the first being the tenth season.
