The Trains are various (two in Go, Diego, Go!) different-colored connected series of vehicles for rail transport that move along tracks. Each one has its own whistle, all but Azul, who did not have one until he won a train race and received one as a prize. The blue (Azul), gray, yellow, and green (Huey) trains are males and the red train (Roja) is a female. The Giant Panda Express is non-anthropomorphic and has no gender, just like a train in real life.

Giant Panda Express


  • Azul, The blue train Choo-y, and Chucho are the only ones that has a name. The Red, Green, Yellow, Gray, Birthday Express, Color Train, and the dancing train have no official name.
    • However, Red, Green, Yellow, and Gray are named as Roja, Huey, Amarillo, and Grandpa (while some refer to the Gray Train as Señor Chugga.), assumed by some fans.
  • Gray’s whistle is technically CN 3254’s whistle which was out of tune during the 1980s and was recorded as a stock sound effect for various pieces of other media, like Thomas and Friends for example for N&W #475, Rocky & Lexi for example.
  • Red’s whistle shares the same whistle sound effect as Emma from Luke the engineer driver which is also used for other media such as the Wuzzelburg express from Wow Wow Wubbzy.
  • Green’s whistle is a stock sound effect from the Sound Ideas website.
  • Yellow shares the same whistle as Green but at a higher pitch.
  • Azul’s whistle is a stock sound effect from the Sound Ideas website.
  • The Unknown Black Train’s Whistle came from South Simcoe Railway #136 it was recorded as a stock sound effect for various pieces of other media. In fact, the Unknown Black Train’s whistle had also been used as Connor & Porter’s whistles from Thomas and Friends.
    • Coincidentally, Thomas and Friends aired on Nick Jr.
  • Choo-y and the Color Train share the same whistle sound effect as Azul, but unlike all the other steam trains, they have no side rods.
  • Unknown Blue Train 2

    Unnamed Blue Train

    Red, Green, and Gray’s voice actors are unknown. since the end credits at there debut did not feature their voices. while Azul, Chucho, The Birthday Express, Choo-y, and The Dance Train have confirmed voice actors. The Panda Express, The Circus train, The Yellow Train, The Doggy Train, The ABC Animals Train, the Unknown Black Train, the Unknown Blue Train, and The Shape Train have no voice actors at all because they do not speak and/or do not have a face (however, the Shape Train does have talking shapes in it).
  • Azul, Green, Yellow, Gray, Chucho, The Birthday Express, Choo-y, Color Train, Doggy Train, and Baby Bubble Train are males. Red and The Dance Train are females. The Circus Train, ABC Animals Train, Shape train, and Giant Panda Express have no genders at all because they don’t talk or have a face however The Shape Train has male and female talking shapes on it. The Unknown Black Train and The Unknown Blue Train’s genders are unknown however it is possible that The Unknown Black Train and The Unknown Blue Train are males because of the eyebrows over there eyes and The Unknown Blue Train’s mustache even though the engines don’t speak coherently.
  • All of the engine’s designs are a freelance design so they are not based on a specific prototype. However, the dancing train bares a slight resemblance to the F7 Diesel engines and Chucho and the Giant Panda Express bares a striking resemblance to the F40PHs and the SD70Ms only shortened a bit and a whistle was added despite that they are diesels. The Unknown Black Train on the other hand somewhat bears some resemblance to a Class BR 91 tank engine from Germany. The same is said with the Unnamed Blue Train.
