Nose to Nose on the Line

I steamed out from between the felt slippers, ready for my morning run across the polished bedroom floorboards! Halfway to the doorway, I braked sharply—another blue tank engine was charging right down the single line straight toward me! Without backing down for a second, I surged forward with full boiler pressure to claim the right of way. Clack! My front buffers bumped solidly against a cool, smooth sheet of glass. The other engine stopped at the exact same instant, resting nose to nose against mine. I blinked, and the face in the glass blinked right back! It was only the wardrobe mirror, but my buffers polished the glass to perfection!
