Thomas stops just in time and asks the truck if he was okay, but the truck said "All I can see is another truck's backside!", so Thomas jumps on to a different track and heads on his way. He arrived at a small yards and backing next to him was an Cab-Forward Experimental Engine named Bertieberesufferfuffersford and starts talking, so Thomas decides to leave the Mainland and return to Sodor and runs off, leaving Bertieberesufferfuffersford all alone.
