Trivia

 * On the Steamies vs. Diesels DVD, Spencer is mistakenly called a diesel, even though he is a steam engine. This is because in the game, Spencer says he does not have a whistle, but has an electric horn instead. However, his picture clearly shows him having a whistle.
 * Spencer's whistle is a stock sound effect of a GWR whistle.
 * Even though Spencer's tender wheels are black, most merchandise ranges have them blue-grey/metallic silver.
 * Spencer's Hornby model incorrectly features him with black wheels. All other merchandise models have him with correct silver wheels.
 * In his The Great Race promotional video, it states he is the holder of the world speed record for steam locomotives. In the actual special, it is stated that he is a former world record holder.
 * Spencer is the first steam engine to be the main antagonist in a special, with that special being Hero of the Rails.
 * At many Day Out with Thomas events, Spencer has Mavis' face.
