Clearing the Apple Boulder

I am running perfectly, and I am definitely an engine through and through! I rolled right off the rug onto the smooth hallway floorboards to test my speed. Right by the doorframe, a round red apple was resting in the way. I certainly didn't try to eat it—engines need tracks, not tummies! Instead, I revved my wheels, lined up squarely, and gave it a determined push with my front buffer. The big fruit wobbled and rolled along the wood like an enormous red boulder before settling safely against the wall. The main line is clear, and I am ready for any cargo!
