Those 3 Trucks

Those 3 Trucks are minor characters in T&F Series.

Truck 1
Truck one (Also known as Snobal) loves playing pranks on other engines. He doesn't try to harm anyone, and tries to help engines when they are in danger. Truck 1 talks in a high pitch voice, like other trucks on Sodor.

Truck 2
Truck 2 (Also known as [B]en) is not as intelligent as the rest of the crew. He is usually very delayed and he doesn't pay attention to anything that is being told to him. He is quite nice too, and like Truck 1, he tries to help other engines. Truck 2 starts every sentence with a "Duhh..".

Van
Van (Also known as Block) is the strongest out of the 2. Like his name, he is a van, but unlike other vans, he has a sticker on his side that says "A Better Name Than That". He talks in a deep voice because he is "going through puberty". His brakes are much stronger than the other trucks, and he also likes to help other engines.

Truck 1 and 2
Truck 1 and 2 are Tomy and/or Trackmaster troublesome trucks. Truck 2 has a printed face.

Van
Van is a Tomy van with a sticker on his side. His eyes are always shut.

Trivia

 * Those 3 Trucks are a BFDI reference to "Those 4 Guys". They are quite alike except there are only 3 trucks instead of 2. Their names are also similar to 3 characters in Those 4 Guys (Snobal = Snowball. [B]en = Pen (Pen's "legal" name). Block = Blocky).
 * The sticker on Van is from BFB. It's a name of one out of the eight teams in BFB.
