The three trucks or cargo cars are referred to reside at the Blue Mountain Quarry in the upcoming film.
The orange truck carrying a sign has printed text on its sides reading the name of the quarry whilst the second appears to be a flatbed.
The third meanwhile is red and holds mountain rocks which can attach the Blue Mountain Quarry sign together.
Blue Mountain Quarry Blast hits toy shelves worldwide soon.
Thanks to SteamTeam for the alert.
