TrackMaster Crash & Repair Diesel 10 from Fisher-Price shows two different sides of this engine! Sometimes Diesel 10 runs into trouble on the Island of Sodor, and now you can see him transform to reveal damage after a risky railway collision! Attach the included impact boulder to any piece of track, then send Diesel 10 racing into it. As his bumper strikes the boulder, watch his face flip to reveal tarnished features and a concerned expression while his panel opens and his crane pops up! He'll push past the boulder and continue on his way until you repair him. To fix the damage, just pull his bumper, close his panel, adjust his crane, and he's good as new! Children ages 3Y+. Requires 2 AAA batteries.
