Driver drive faster and make a good run
Down the Springfield Line under the shining sun.
Fly like an aeroplane, don't pull up short
Till you brake for Grand Central Station, New York.

 Grand Central Station itself is a very appropriate setting for a love poem. It is generally regarded as one of the most beautiful train stations in the world.
