Long story short, you are a new engine working on the Skarloey Railway, You were doing your job pulling freight cars and by the time you were carrying them you went up the hill but your load seemed to be a little heavier.

Then you saw a kind engine named Peter Sam, He was there to help you, He smiled at you.

"Oh you are the new engine, let me help you push them up a bit!" He said to you.

Peter Sam was at the back pushing your freight cars as he was helping you carry them, You smiled as he was helping you as he chuffed slowly and carefully.
